Investigation of Surface Preparations to Enhance Photon Doppler Velocimetry Measurements
Abstract
The work described in this report compiles empirical measurements of the intensity of 1.55-micrometers light reflected from numerous materials prepared with varying surface finishes over a range of incident and detection angles. The data are desired to construct a guide for conducting Photon Doppler Velocimetry measurements, which necessitates a prediction of the intensity of Doppler shifted light that will be reflected from a surface to optimize the measurement. It was found that the intensity of reflected light could be sufficiently explained using the law of reflection coupled with a coefficient of reflection that is specific to the material. It also provides a technique for empirically measuring the latter.
