Phasing the Telescope
Large telescopes suffer from aberrations and design flaws and
telescopes deployed in space
can suffer from damage during assembly as well
- The atmosphere distorts the medium thru which ground telescopes
view distant objects, and the fixing medium distorts images in microscopes.
Adaptive optics solves these problems with
mirrors made up of many adjustable sections.
These are called mosaic telescopes.
- Must select the optimal adjustment of the mirrors
so that the reflected wavefront is optimally phased and the signal is of
model to describe the telescope phasing problem was developed by
Ribak, Adler and Lipson in 1989, using an analogy between
the optimal reflected
wavefront and the groundstate of a solid-on-solid model.
