1. A method for obtaining a three dimensional, three component velocity measurement of particles moving within a flow volume, the method comprising:
providing a time sequenced series of images of a flow volume containing at least one particle resident moving within a fluid, wherein depth information of the at least one particle moving within the fluid volume is color coded into the images as a consequence of reflected lights from the at least one particle; and
tracking a three dimensional (3D) trajectory of the at least one particle by analyzing a two dimensional (2D) spatial motion of the at least one particle based on (1) the time sequenced series of the images and (2) a change in color of the reflected lights from the at least one particle,
wherein the reflected lights from the at least one particle and reflected lights from other particles of the flow volume are focused on a same sensor plane of a single optical device for processing.
