Abstract
A system and technique are described, for use in optical monitoring of objects. The system comprising: a collection unit comprising at least one optical arrangement and at least one detector array arranged for defocused collection of light returning from a selected region on the object; and image data collection circuitry configured for receiving electronic signals associated with data piece collected by pixels of the at least one detector array and for generating output data indicative of correlation function between image frames collected by the detector array at two or more different temporal instances. The technique thereby enables determining of correlation between image data pieces with reduced computational complexity.
