Claim 1
Independent Claim
108 words
A NONLINEAR ELECTRO-OPTICAL SYSTEM THAT COMPRISES: A PHOTOSENSITIVE DEVICE HAVING AN ELECTRODE THAT NORMALLY WOULD BE DRIVEN TO CURRENT SATURATION BY LIGHT IMPINGING UPON THE ACTIVE AREA OF SAID DEVICE, SAID LIGHT HAVING A RANGE OF INTENSITIES ABOVE THE MAXIMUM INTENSITY THAT WILL NOT DRIVE SAID ELECTRODE TO CURRENT SATURATION; AND AN OPTICAL FILTER INTERPOSED BETWEEN SAID IMPINGING LIGHT AND SAID ACTIVE AREA, SAID OPTICAL FILTER HAVING A DENSITY INCREASING FROM A FIRST DENSITY THAT WILL PERMIT CURRENT SATURATION OF A CORRESPONDING PART OF SAID ELECTRODE BY SAID LIGHT TO HIGHER DENSITIES THAT WILL PERMIT PARTS OF SAID ELECTRODE TO RESPOND TO SAID LIGHT WITHOUT BEING CURRENT SATURATED.
