Title: Iterative absorption threshholding optical quantizer
Inventor: RICHARD A FIELDS
IPC: G02F7/00
Filed: 2000-06-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical quantizer adopting chain type optical thresholding devices arranged within a propagation route of a light input beam for quantization. SOLUTION: The respective optical thresholding devices 16 are saturated and become transparent when the intensity of an incident light beam 12 exceeds a prescribed threshold level designed for the devices. When the input beam 12 saturates the optical thresholding devices 16, the devices output an instruction signal 22 to identify the saturation. The input beam 12 propagates by being accompanied by some attenuation generated by this saturation, passes the devices 16 and is made incident on the succeeding devices 16 existing within the chain. Finally, the attenuation of the input beam generated by many times of the saturation degrades the beam intensity to the threshold level of the devices 16 or below. The number of the instruction signals gives the intensity instruction of the input beam 12.  The devices 16 are capable of imparting the light or electric instruction signals according to the kinds of the optical thresholding to be used.
