Research Abstract

In order to expect the purpose of this application research to an important problem called the air spectrum by the direct detection of an extrasolar planet, it is carrying out the development actual proof of the cryogenic temperature deformable mirror carried in an infrared space telescope.
In the drive system of a deformable mirror, it is Micro-Electronic Mechanics System. (MEMS) the system was adopted. And the design in consideration of the heat stress which is the biggest problem at the time of cooling was able to be performed, and DM of the many elements (1000 elements) which operate by cryogenic temperature (5K) was able to be made and examined.
