Abstract

A variety of algorithms utilized in the alignment of segmented telescopes were developed for and implemented on the Keck telescopes in the 1990s. The algorithms associated with the Keck segmented primary mirrors are very similar to those that will be used for the Thirty Meter Telescope (TMT). However, there are alignment or related wavefront measurement tasks associated with the TMT secondary and tertiary mirrors for which the corresponding Keck algorithms either did not exist or are not adequate for TMT. We discuss two particular algorithms associated with the TMT secondary and tertiary mirrors.
