Indirect geometry measurement with fluorescence particles

Optical measurement techniques provide fast and precise geometry measurements, but only if sufficient light energy is reflected from the object surface to the photodetection unit. For this reason, specific measurement techniques must be developed for each type of surface. To avoid this problem, a novel approach of indirect geometry measurement will be developed in this project.

The approach is based on measuring the geometry of a surrounding atmosphere instead of measuring the object surface. The atmosphere is excited with a laser using fluorescent particles and the fluorescent light is measured with a microscope. The aim is to investigate how suitable the approach is for different atmospheres and materials.
