Abstract

CI has developed a modular optical system, which provides the sensor stimulus to obtain the required quantitative spectral response of single detectors, detector array engines and camera systems with small to large aperture optics. The system includes interchangeable sources, Circular Variable Filter scanning monochromator (CVF) and collimating and focusing optics to project monochromatic radiation (in focused or collimated configuration, according to need) towards the sensor. When spatial patterns are also used on the focal plane, the Unit Under Test (UUT) is fully characterized in both spectral and spatial domains. The systems’ description and some examples of detector and camera measurements have been published in SPIE Vol. 12737, 127370O-1, 2023, but here we add a measurement of MTF versus spatial frequency at different wavelengths of a commercial infrared camera in the range of 3 to 5 microns.
