How do astronomers get clear pictures of the stars when there's the earth's atmosphere in the way? Today we get to see adaptive optics in action.

Great video!

Thanks Mr. Andersen 4 this brilliant class. I want more technical information about. 4 ex. in the secondary mirror (or other intermediary), how mutch must be the distortion of the surface? Other: It's possible to use the electrostrictives property of quartz about? (to build the secondary or some terciary mirror) So you needs not more than small silvered surfaces connected to computer, like a net I want your FB friendship, to ask more.

this vids kicked ass. asked really good questions and got good closeup shots. thanks for interviewing this guy! Nobel Laureate John Mather visited out school and at one point mentioned adaptive optics and how it was classified in the us but later recreated in france where the technology was then distributed...

It'll be great when the deformable mirrors get affordable to amateur astronomers. For now, wave front sensors require guide stars but I wonder if a wavefront sensor could ever work on assuming some stability in the undistorted image like speckle imaging does. Requiring a powerful laser will always be a deal breaker for amataurs. If the wavefront could be detected and given to an affordable deformable mirror, amateur astronomers could finally see lots of detail.
-
Since the computer must first see how the image is being distorted and then move the mirror, how does it compensate for that time lag?
-
it's a great idea to change the shape of the mirror in accordance with the atmosphere. this is a simple but very powerful method for viewing distant galaxies

Have we just simply looked over BCI solutions? Piezoelectricity arrays like the ones used for telescope correctional lenses may be a BCI solution because pressure or sound waves may also be present in neuron activity according to Thomas Heimburg from the Niels Bohr Institute at Copenhagen University and Andrew D. Jackson, who is an expert in theoretical physics. For now BCI electrodes scar over and it is not a lasting solution. So, is solving the problem of sustainable BCI as simple as looking at the problem differently with already existing equipment. Has anyone during brain surgery tried using piezoelectric stimulation on the brain during surgery? Keep in mind, pun, sound focused stimulation to mouse nerves to move their tales has already been done. Looks like it is worth the added 30 seconds in a brain surgery to explore this question, and see if sound is a feasible BCI alternative

hello, can you please instruct me as to where i can get or to which companies sell such "phase screen wheels" as is presented here?

A very good explaination of adaptive optics!

That's very close to to setting the "mode" on a beam through a particle accelerator, difference is that the ''deformal'' mirrors on the last resonator I set up were manually set and liquid cooled. But when we set the mode we were always looking for a "O" as the footprint not a circular dot because the assist gas needs to follow the wave front when cutting and the particle beam would burn the mirrors and lenses and end up warping them or melting them if the beam became concentrated before leaving the final focal point lens of the head. The resonator would cost upwards of 150k which consisted of 1 output-mirror(first pooiont at which the mode could be measured), One Rear mirror and 6 bending mirrors with correcting centers which all surround the turbine pressure generator for the plasma gas containment. The beam was bent 6 times before leaving the resonator for maximum particle accuracy. Every change in direction of the beam that is made before leaving through the output mirror makes the particles travel more and more straight. If there were only an output and a rear how many tines would the light bounce between the two mirrors before reaching the output mirrors resistance level? Baseicaly you get a output beam of peak performance just outside the resonator but 100 feet away the beem is no longer optimal because of widening like a laser pointer. With all the other bending mirrors in the resonator there is that much more correctability and trueness to the output beam. If we had liquid cooled "deformal" mirrors that would be the cats ass. For telescopic use; can the curvature of the Earth's atmospheric surface not be worked into the calibration as well as smooth the and even the wave front? And as well can we use a second and even perhaps a third or fourth highly sensitive "deformal" mirror or even mirror array for digital adjustment of magnification and ? zoom ? ...this implemented into both systems of focusing visual ability and the focus of particle acceleration to a completely new level of accuracy? This is truly the next step in the weaponization and optical observation. With this type of setup it would be possible to correct the existence of interference particles between the output mirror and the target by an automated (sensor/programmed controller/servo-adjusted/correction-checking/loop) setup that would allow the beam (or image to be viewed) to be bent around minor interferences that otherwise distort the focus of the image (or output beam). One would think that with what we already know in means of technology we should be able to assemble an apparatus with ability to see a mouse on thee back side of Pluto and focus a particle beam to neuter him too. As well the same technology with proper calibration could be used to measure the distances between us and anything or the distance between any two points in the universe we can see. The same technology can again be employed to deliver energy wirelessly to a space faring vehicle as propulsory fuel. Further more I here present that geothermal energy sources throughout the solar system and other energy sources could be utilized to extend the range of said space faring vehicles by installation of energy beam emitting stations that would operate autonomously by receiving pings like a cellular phone network then once the ping is received the network would use the closest tower to beam propulsory energy to the vehicle. This technology after final development and thorough refinement could also be used to autonomously explore, scout, and expand our travelling range while constantly sending a report of progress back to us so we know what to expect and where to expect it in space exploration. It would be used as a research refinement tool so we would know where to and not to find whatever it is we may be looking for and it could also be made untraceable to such an extent that it would in its tamper proofing be made to report its origin as its direction of exploration or as any where we want to make tracing of its origins impossible for an alien race that may discover it and investigate it. A decoy could be also made at the reporting place of origin to allow us to monitor the reaction of the alien species to our existence. As well other measures could also be taken... An autonomous space fence could be employed within the very same network to defend our territory from outside aggressors by making the propulsory fuel delivery system adjustable to a weapon grade beam devise and as well kinetic weapons systems could also be installed to further backup these autonomous beam stations. The exploration units could be designed to work completely around any life form it found so as not to encroach on its natural self set boundary as well since all space is designated free for development of non space faring, non threat localized natural wild life throughout the universe. Only species with sentient ability to destroy everything and overrun other types of life in the universe in an aggressive manor need limitation by universal law because from the general sentient beings curiosity fulfillment need of an explorer and respecter of the universe is come the Universal living beings right to happily exist naturally just so more diverse things are out in the universe for ever to be seen and experienced by all space farers because once there is nothing left to discover and nothing left to invent and the only driving factor left to us becomes need of resource to maintain and everything has been cataloged and learned we will become pretty bored if we have to look at the same thing everywhere. Travel and diverse leisure activities will inevitably become the focus of our existence. Can't wait.

Wow, excellent video. This is insanely cool.
-
This explains it wonderfully! The explanation of how the mirrors work is something we always wondered about. Nice job.
-
so the atmosphere acts like water like when you're looking down at a fish it's all wobbly and distorted, does it also do that light refracting gimmick or is it too thin? i hope someone makes some damn high tech future sunglasses to fix that to make bow fishing easier cuz i wanna try, also wanna try using a harpoon or spear.

Nice mustache
-
Really interesting...and well explained by Masen.
-
...And speaking of boiling rage, don't get me started on the SF shows that show twinkling stars through the starship windows.
-
This is some very cool shit!
-
Great video! But I have a question though. Why have a physical shape shifting mirror? Wouldn't be much easier and faster to have a program that grabs the reflected image, calculates the distortion and generate an image on the screen with a corrected image?
-
Really cool video. I hope you continue to make more.

Awesome presentation!
