Advanced Wavefront Sensing Techniques for Next Generation Adaptive Optics Systems

Canada has committed funding and is a major partner of the Thirty Meter Telescope (TMT). When completed, TMT will usher in a new, exciting era of optical and near-infrared astronomy. To make the most of TMT, we will need to incorporate Adaptive Optics (AO) systems to compensate for turbulence in the atmosphere. AO on TMT should allow us to take high resolution images and integral field spectroscopy of everything from asteroids in our solar system, to planets around other stars, to stars orbiting around the black hole in the center of our Galaxy, to stars moving in the gravitational potential of other galaxies, to galaxies billions of light years away as they exist in the era of peak star formation, and to “first-light” objects from the early Universe.
