Abstract

In the testing technology and analysis, laser aided lightoptical methods are increasing the conventional testing methods in a multivarious way. The opto-thermal hybrid microscope is a device which gives one the possibility to reveal point imperfection; for example in surface coatings. Also a differentiation between surface- and sub-surface defects can be performed, by comparing the thermal surface radiation with the intensity of the reflected part of the exiting light.
