Abstract
The CALIPSO LIDAR is a two-channel visible/infrared, polarization sensitive space based instrument. The mission specifies a lightweight, thermally stable platform for the lasers, 1-m telescope, and LIDAR instrumentation. Stability requirements include ±26 μrad boresight stability between the telescope and the laser as well as ±10 μm optical bench thickness stability and ±70 μm stability of components on the optical bench. The environment for these performance criteria is a 0 C to 50 C space environment. In order to demonstrate performance, a laser tracker, a laser comparator, and an electronic autocollimator were used in conjunction with an environmental chamber to measure the stability of the structure over the operating temperature range.
