OPTOELECTRONIC SYSTEM FOR DETERMINING SPECTRAL-ENERGY PARAMETERS AND COORDINATES OF INFRARED LASER RADIATION SOURCE Russian patent published in 2017 - IPC G01S3/781 G01J3/45 

FIELD: physics, instrumentation technology.

SUBSTANCE: invention relates to instrumentation technology and an optoelectronic system for determining spectral-energy parameters and coordinates of a laser radiation source. The system includes two optical channels, a matrix photodetector, a cooling system, detection, coordinate and spectral units. The first optical channel includes an optical device with a wide angle of view, an interferometer and a first lens. The second optical channel consists of a second lens and a transparent plate with Fresnel reflection, installed at an angle of 45° to the optical axis of the second lens. The image of the laser radiation source and the fringe pattern formed by the first optical channel are simultaneously projected on the photosensitive surface of the photodetector. The coordinate and spectral units enable simultaneous determination of spectral-energy parameters and coordinates of the laser radiation source on a single video frame with images of said source and fringe pattern.

EFFECT: enabling simultaneous determination of spectral-energy parameters and coordinates of a laser radiation source.
