Active thermography inspection of protective glass contamination on laser scanning heads
Original language description
Industrial lasers are an expanding technology of welding and other material processing. Lasers are often used with optical scanning heads which provide more versatility, accuracy and speed. The output part of the scanning head is covered by a protective glass which might get contaminated by various particles from the laser processing. This decreases the transmissivity of the glass and it can affect the production quality. The contamination needs to be checked regularly but a visual inspection might not always be effective. This paper proposes two alternative methods of inspecting the protective glass - flash-pulse active thermography and laser active thermography. They are based on the thermal excitation of the glass and measuring the response with an infrared camera. The experimental setup and practical results are described and the advantages and disadvantages are discussed. The presented methods proved to be effective in detecting the contamination of the glass.
