Three wavelength quantitative imaging systems |
摘要 |
An optical system includes more than two optical interferometers that generate interference phenomena between optical waves to measure a plurality of distances, a plurality of thicknesses, and a plurality of indices of refraction of a sample. An electromagnetic detector receives an output of the optical interferometers to render a magnified image of at least a portion of the sample. A controller reduces or eliminates undesired optical signals through a hierarchical phase unwrapping of the output of the electromagnetic detector.
