Imaging Of Surface Microstructures Of Materials

Abstract

This paper describes functionality extension of a LIBS (Laser-Induced Breakdown Spectroscopy) device. Subject of the extension is surface microstructure imaging of materials. The first method uses illumination module. The module contains four sections, each individually controlled. Each segment can be regulated or switch on or off independently. Thanks to illumination from several angles one obtains better image of the surface. This is caused by visible change sample microstructure. The second method of surface optical detection uses collinear illumination.
