Abstract

The Advanced Sensor Evaluation and Test (ASET) Facility is a system for the calibration and exercise of infrared sensors under conditions simulating those of outer space. Sensors typically consist of a telescope, detector focal plane array, electronics, and data processing equipment. They normally detect radiation from distant, unresolved objects in the 4 μm to 30 μm wavelength region. Accordingly, the ASET facility comprises two radiant sources, collimating optics to place the sources at infinity, scanning mirrors to permit two-axis control of the test beam, a radiation monitor, and associated control and computer interface equipment. The radiant incidance range over which the sensors normally operate precludes the use of an unattenuated blackbody source. The ASET sources use blackbody emitters in conjunction with various attenuators which are difficult to characterize theoretically. Therefore, an experimental calibration of the facility was performed to determine the spectral radiant incidance in the test beams. The techniques employed for and the results of this calibration are reported here.
