AEDC Focal Plane Array Test Capability
Abstract
The focal plane array test facility provides complete radiometric characterization of detector arrays and hybrid arrays. Most testing is performed in the Focal Plane Characterization Chamber (FPCC), which provides a cold, low background environment for focal plane tests. An injection system on the chamber facilitates a high throughput rate and good economy of operation. Testing in the FPCC can involve either flooding the array with uniform blackbody radiation or focusing radiation on a single pixel. Focal plane voltage output and noise can be measured as functions of source irradiance, bia voltage, focal plane temperature, integration time, chopper frequency, and infrared background. Relative spectral response measurements are made in a test station involving a three-grating monochromator. Most critical performance parameters can be evaluated, including responsivity, noise equivalent input, dynamic range and linearity, radiometric stability, power consumption, recovery time, array uniformity, and crosstalk. In addition, a wide variety of data presentation formats is available.
