THERMAL IMAGING MODULE Russian patent published in 2018 - IPC G02B23/12 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of optoelectronic instrumentation, in particular, to the infrared images into visible ones conversion devices, and can be used as the thermal imaging devices input modules, used in the phased antenna arrays radio-transparent covers monitoring. Device contains lens, in which focal plane an infrared detector is installed, as well as microwave filter made in the form of circular waveguide with inner diameter of at least λ/2, and length of λ. At that, the lens is secured inside the circular waveguide by the nut at a distance of 1 to 100 mm from the waveguide input through the gasket from conductive absorbing material, installed between the lens and the circular waveguide.

EFFECT: invention enables technical result consisting in improvement of the thermal vision image formation reliability and quality.
