Summary:An optical system performs imaging in a transmissive and reflective mode. The system includes an optical interferometer that generates interference phenomena between optical waves to measure multiple distances, thicknesses, and indices of refraction of a sample. Measurements are made through a galvanometer that scans a pre-programmed angular arc. An excitation-emission device allows an electromagnetic excitation and emission to pass through an objective in optical communication with the sample. An electromagnetic detector receives the output of the optical interferometer and the excitation-emission device to render a magnified three dimensional image of the sample.
