This paper discusses the possibilities of laser technology in operations involving the assembly of optical elements, using heat-shrink materials. It is shown that, by choosing the radiation parameters, spatial localization of the heating that is adequate for shaping can be achieved in a polymeric material but still does not result in undesirable heating of the item being assembled. A process is described that uses the proposed method to assemble an electro-optic modulator based on a DKDP crystal.

The time dependences of the surface temperature increment of painted metal objects were studied depending on the thickness of the layer subjected to corrosion, as well as putty, restoring erosion defects on it. Hidden under a layer of paint, they cannot be detected remotely during normal visual observation. At the same time they are well detected by pulsed laser thermography. The experimental data in the work are compared with the results of mathematical modeling. Particular attention is paid to eliminating possible distortions caused by external contamination of the tested objects.
