OBJECT VISUALIZATION DEVICE Russian patent published in 2020 - IPC G02F1/00 H04N5/33 

FIELD: optics; machine building.

SUBSTANCE: invention relates to the field of optoelectronic instrument making and relates to the object visualization device. Device includes an object illumination source, an optical system forming a beam of illumination, an anti-Stokes frequency converter of infrared radiation, an input optical system, a narrow-band interference filter, a photodetector matrix, a signal processing unit and a monitor. Anti-Stokes converter is arranged on the observed object. Optical radiation source used is a frequency-tunable laser which emits in the infrared wavelength range and exciting the anti-Stokes fluorescent emission of the observed object at a wavelength corresponding to at least one of the Fraunhofer lines of absorption of solar radiation.

EFFECT: technical result consists in enabling round-the-clock operation of the device, improved noise immunity and longer range of the device.
