ABSTRACT:
A laser detection system is disclosed. Optical means projects light scattered from a moving localized portion of the beam onto a photosensitive strip. Voltage applied across the strip causes the light generated electrons therein to move through the strip at the same rate as the scattered light from the moving localized portion of the beam projected onto the strip moves across the strip so that all the electrons generated in the strip are detected as an accumulated charge at one end thereof.
