INFRARED COLLIMATOR COMPLEX Russian patent published in 2015 - IPC G02B27/30 G01M11/02 

FIELD: measurement equipment.

SUBSTANCE: complex is designed to monitor and measure parameters of thermal imagers. The complex comprises a lens, a replaceable test object located in a focal plane of the lens, a background emitter, located behind the test object and equipped with an actuating element, a control device, the outlet of which is connected to the actuating element of the background emitter, a temperature processor, the outlet of which is connected to the inlet of the control device, a device to measure test object temperature, the outlet of which is connected to the first inlet of the temperature processor. The replaceable test object is arranged as mirror and is installed at the angle to the axis of the lens, providing for reflection along the axis of the lens of infrared radiation flow, arriving to the test object from the additionally introduced reference radiator, equipped with a device of temperature measurement of the reference radiator, the outlet of which is connected to the second inlet of the temperature processor. Additionally the first and second devices are introduced to measure temperature of the background radiator, the outlets of which are connected accordingly to the third and fourth inlets of the temperature processor.

EFFECT: increased accuracy of contrast radiation level maintenance.
