Measuring Device of Infrared Radiation


In the introduced device an electrostatic field conjugated by a detector and joined with the power source via a resistor is fed on the sensitive element the electrodes of which are in a thermal contact with a parametric voltage-reference diode. The infrared detector automatically operates at maximum pyro sensitivity at the temperature up to which the active element is heated under the effect of infrared radiation in the given (every) concrete case.

Innovative Aspect and Main Advantages

The proposed infrared detector of a new generation automatically operates at a maximum pyrosensitivity in all ranges of working temperature of the active element. It differs from its analogues in its high sensitivity (2.6 * 10-7Kl/cm2К) and operating speed. The method of its obtaining differs from its analogues in its simplicity and moderate price.

Areas of Application

The innovation can be applied in solid-state electronics, particularly, in manufacturing pyroelectric radiation detectors and measuring technology for a phase transition control.
