| Popis: | A 32/spl times/32 array of photosensors with pulse frequency outputs uses standard 2 /spl mu/m CMOS technology. The photosensors use pulse-frequency encoding to achieve a linear dynamic range of 10/sup 6/ in optical energy. Power dissipation of the photosensor is proportional to the frequency of the pulse outputs, and under typical illumination and bias conditions, the entire 32/spl times/32 array dissipates > |
