Infrared Sensor Test Requirements And Critical Issues

The primary focus of this paper is long wavelength infrared sensor calibration. The success or failure of a calibration program is determined long before calibration time by the quality of the prior sensor design and test program. Failure to adhere to any one of several important test principles can lead to difficulties in calibration and flight. If test and calibration are not given high priority during sensor design, flight performance may be compromised because calibration and functional testing will be difficult. A test and calibration facility is virtually required to accomplish the many different tests essential for sensor acceptance and calibration. A number of critical issues remain to be resolved, and a number of new requirements must be accommodated in future test and calibration facility design.
