Improved Facility for Optical Detector Characterization

T Flournoy, George P. Eppeldauer

Abstract

The detector characterization and calibration facility of the Army Primary Standards Laboratory (APSL) has been extended. In addition to the traditional filter and monochromator based spectral measurements, laser-based sphere sources and high performance irradiance meters have been developed to extend the spectral coverage and signal dynamic range of detector and radiometer calibrations. The modulation of the laser sources provides a platform for extending the dynamic range of frequency dependent responsivity testing. The newly developed high accuracy radiometer standards make it possible to perform spectral power and irradiance responsivity measurements with an expanded uncertainty (k=2)1 of 0.5% or smaller.
