DEVICE FOR ADJUSTING AND CHECKING OPERABILITY OF INFRARED EQUIPMENT OF REMOTE OBSERVATION SYSTEMS Russian patent published in 2024 - IPC G01J5/90 

FIELD: measuring.

SUBSTANCE: invention relates to photometry and relates to a device for adjusting and testing infrared equipment of remote observation systems of spacecraft and aircraft. Device comprises an underlying surface, a measuring sensor and a software control device. Underlying surface is made of electric heating elements of a rectangular shape with a measuring sensor in the form of a temperature sensor and control leads, which form an active controlled infrared areal target placed on a metal frame. Heating element is a multilayer structure of heat-insulating material, a foil-clad reflector and an infrared film heater. On the surface of infrared film heaters there is a working surface of a heating element in the form of an aluminium sheet, on the surface of which temperature patterns are formed. Outputs of temperature sensors are connected through input modules to a control cabinet connected to an automated workstation made in the form of a software control, monitoring and documentation tool. Target is rotatable in azimuth through an angle of not less than 180 degrees with a turn pitch of 1 degree.

EFFECT: higher accuracy of measurements.
