Motion Scan and Data Collection Methods for Electro-Optic System Testing
This article discusses different scanning patterns and approaches that can be used to measure an electro-optic (EO) sensor’s performance. Measurements of sensor resolution, distortion, field-of-view (FOV) size, minimum resolvable contrast and minimum resolvable temperature (in the case of IR cameras) are all examples of performance metrics that are measured with these tests. Executing scan tests…
