Abstract: A description is given of an infrared laser defectograph (flaw detector) based on the use of improved temperature sensitive luminescent screens which make visible the CO₂ infrared laser radiation transmitted by an investigated object. This defectograph can be used to study the internal structure and microdefects in semiconducting materials which are opaque to visible light.
