Device for tracking movement of microscopic and sub-microscopic objects in microscopic volumes

摘要

The device uses two coherent beams which are crossed to form moving interference patterns. The frequencies of the beam in each pair are different, so that the scattered light intensity of a fixed object varies with the difference frequency of the beams, and each positional variation of the object perpendicular to the interference pattern can be detected as a phase change in the scattered light. A method for using the device is also claimed.
