Material Dispersion Influence on Chromatic Sensors Measurement Accuracy

Popis výsledku v původním jazyce

The use of non-contact chromatic confocal sensors in industry is nowadays very widespread. These sensors are based on the dependence of longitudinal chromatic aberration of optical systems on wavelength and measurement systems based on this principle give very good and accurate results in the case of pure reflection of the measuring beam from the investigated object (e.g. reflection from metals etc.). In case we need to measure the thickness of transparent materials (e.g. plan-parallel glass plates) andsimultaneously we want to measure the topography of tested object surfaces then chromatic sensor based measurement systems produce errors due to the dispersion of transparent media (e.g. glass) of measured objects. The work deals with a physical originof these errors and analysis of the influence of these errors on the accuracy of measurement using chromatic sensors. Relations for quantitative evaluation of these errors are derived.
