Manually portable apparatus enabling high-resolution two-dimensional infrared imaging of remote non-contacting, targets is described. An on-axis optical subsystem consists of a single, single-faceted planar scanning mirror that is reciprocable by stepper motors about two orthogonal axes. Oriented at approximately 45° relative to the mirror's line-ofsight axis to a target, the scanning mirror reflects infrared energy incident thereon toward a spherical converging mirror which may be manually focused to change the distance between it and a single-element, non-cryogenically cooled heat-sensitive, detector located behind the scanning mirror. An ADC a, microprocessor and a motor control circuit …
