22 September 1983 Optical Characterization Of The Lockheed Sensor Test Facility
Author Affiliations +
The recent development of a new long-wave infrared (LWIR) sensor test facilityl presented a number of interesting problems during the course of the optical system alignment. This facility, the Lockheed Sensor Test Facility (STF), was designed primarily for calibration and system testing of LWIR sensors in the 5 to 30 pm range. It combines a low background vacuum chamber with a unique wide field-of-view optical system. This paper will discuss the facility and its optical instrumentation with emphasis on assembly, metrology of alignment, optical characterization, tasks complicated by manufacturing oversights, and an aluminum support structure which shrinks over 1 in. when it is cooled 250 K to the cold operating temperature.
