THERMAL IMAGING FLAW DETECTOR Russian patent published in 2016 - IPC G01N25/00 G01J5/60 

FIELD: measuring equipment.

SUBSTANCE: thermal flaw detector comprises an optical heater for thermal stimulation test object imager, a computer, a rotary actuator, a rotary mirror made of a planar insulating substrate and two polished metal plates, such as aluminum or copper, attached on both sides of the insulating base. Invented device uses a rotating mirror that during the heating of the object of control is set at an angle of inclination equal to 45°, between the normal to the surface of the rotary mirror and the normal to the surface of the inspection object and an inclination angle equal to -45°, during the registration period of the temperature field control object imager that provides the highest possible power density of the heat and the lack of geometric distortion of the image of the object of control.

EFFECT: improving the accuracy of the data.
