Patent abstract
In a compact optical device, a light emitting area of a light source and a light sensing area of a detector are placed in proximity. The detector receives part of a beam which is reflected back to the source from a sample. As a result, a beam splitter is no longer needed. By eliminating the beam splitter and packing the light source and detector in closeness, dimensions of the optical device are reduced.
