RECEIVER OF IR AND THz RADIATIONS Russian patent published in 2018 - IPC G01J5/20 

FIELD: measuring equipment; radio engineering and communication.

SUBSTANCE: invention relates to the radio measurements technique. Proposed receiver is designed to measure the spatial-energy characteristics of laser radiation at wavelengths of 2.08–16.6 mcm, 0.33–0.37 mm. Receiver of IR and THz radiation, containing a flat hermetically sealed glass-metal housing, consisting of a base with leads, which are electrically connected to the corresponding contact areas of the substrate, and a lid with a window transparent to the registered radiations, the substrate is placed in front of the window, on which the thermal-sensitive elements are placed, from the VO_x film, in the form of a mosaic filling the receiver's circular reception area, each element has a signal and common electrodes connected to contact pads located along the perimeter of the substrate, on the back side of the substrate a film compensation element made of VO_x with electrodes is located. At that, on the front surface of a mica substrate with a thickness of 40 mcm a two-dimensional film aluminum array with square cells is located that fills the receiver's circular receiving area, the two-dimensional array period is determined by the relation d=a+b=0.23–0.25, where a is a cell size, a=0.22 mm; b is the width of the jumper between the cells, b=0.03 mm, along the of the substrate perimeter there a film compensation element is located made of a VO_x film, which dimensions are similar to the temperature sensitive elements that are placed on the underside of the substrate under the cells of the two-dimensional array on the receiver receiving area.

EFFECT: technical result of the proposed device is in extension of the spectral range of wavelengths.
