Abstract

Many modern electro-optical systems incorporate multiple electro-optical sensors, each having unique wavebands, alignment, and distortion. Traditional laboratory testing requires multiple measurement setups for metrics like inter-channel sensor alignment, near/far focus performance, color accuracy, etc. In this study, a calibrated scene is developed for objective measurements of multiple electro-optical cameras from a single mounting position. This scene uses multiple targets (size and shape), multiple flat fields (blackbodies and spectralon panels), and temporal sources. Some targets work well in both the emissive and reflective bands, allowing for accuracy relative distortion to be measured. Specific attention was given to testing in the presence of scene-based algorithms such as auto-gain/level/exposure, where bright and dark objects are used to drive dynamic range. This approach allows for various measurements to be taken simultaneously and efficiently.
