Claim:
1. An optical sensing system for detecting a moving object passing through a volume of interest, said system comprising: an emitter which emits a light beam through the volume of interest, said light beam having a normal intensity; an expanding lens which expands the diameter of the light beam; a collimating lens which collimates the light beam; a mosaic detector having an array of detecting elements along a length and width; a decollimating lens which focuses the light beam on the mosaic detector having an array of detecting elements along a length and a width; wherein each detecting element is configured to independently detect changes to the normal intensity of the light beam; a processor which receives and processes inputs from the detecting elements; providing detection of the object's motion, velocity; and size along the length and width of the mosaic detector.
