Titel
Application of optothermal hybrid microscopy in nondestructive and noncontacting testing of coatings
Abstract
In the testing technology and analysis, laiser aided lightoptical methods are increasing the convential 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.
