Advanced Test Systems for Production Testing of Cameras With Day/Night and Visible/NIR Capabilities

摘要

This paper presents the latest developments in instrumentation for military fixed and head-mounted camera test and evaluation. SBIR has completed development of a new variable contrast test system for evaluating camera dayight mode performance. The system utilizes an integrating sphere with variable, full field-of-regard background illumination combined with a collimator, controlled ambient background, a set of variably illuminated chrome-on-glass targets, and visible/NIR filters. The system employs precision azimuth and elevation motion stages to facilitate FOV size and uniformity evaluation. SBIR''s IRWindows™ software provides a series of automated tests such as boresight, MTF, MRTD, FPN, pixel defects, spectral response and dynamic range/contrast. The system uses a second integrating sphere with a variable luminance control to measure FOV uniformity, individual pixel response, and automatic brightness control efficiency.
