Bachelor/Master Thesis: Do the surroundings speak? Gas-phase fluorescence for indirect optical geometry measurement

Gas-phase fluorescence for indirect optical geometry measurement
Just as in analog photography the final image is created from the negative, the surface geometry can be determined from the negative impression of a measured object in a surrounding medium – similar to a dental impression at the dentist. The innovative approach of measuring not the medium itself, but its impression in the surrounding fluorescent, gaseous medium, is being pursued in the research project on indirect optical geometry measurement (InOGeM).

Fluorescence occurs in solid, liquid, and gaseous media, but gas-phase emitters rarely remain volatile under ambient conditions. Recent studies, however, report fluorescent dyes that can sublimate at low temperatures retaining their strong emission in the gas phase.

The aim of this is to apply gas-phase fluorescence to the InOGeM approach.
