DYNAMIC SCENE SIMULATION DEVICE Russian patent published in 2023 - IPC G02B27/30 G01M11/00 G02B26/08 

FIELD: optical instrumentation.

SUBSTANCE: invention relates to optical instrumentation and can be used as part of measuring equipment for testing and evaluating the characteristics of optoelectronic systems (OES) designed to operate in the visible and infrared spectral ranges. The device for simulating a dynamic scene consists of an illumination system located along the beams, containing a radiation source with a radiation intensity control unit, a mirror tunnel and an image transfer system containing a concave mirror, a micromirror matrix with a micromirror position control unit and an output lens. In the lighting system, the mirror tunnel is made in the form of a truncated tetrahedral pyramid with a rectangular base. The concave mirror of the image transfer system is made spherical and a second concave spherical mirror is additionally introduced. The output lens is made collimating.

EFFECT: device provides the ability to test wide-angle OES by increasing the linear field of view while ensuring optimal matching with the system under test.
