  • Similarly, when there is a difference in the optical path from the probe to different portions of the surface of the specimen (e.g., a height variation, perhaps in the form of a step on the surface of the specimen, or different regions with different indices of refraction) the reflected illumination will be phase shifted with respect to the probe emitted illumination.
