This paper describes a novel photodetector, based on a new charge inte- gration concept, "persistance-integration". This photodetector is found tobe suitable for imaging low-speed or static objects at low light levels. Model of the sensor, based on the experimental results of a single pixel device is presented. Dynamic range is about 110dB. Linearity γ≃0.71. Signal gain of the device can automatically increase with a decrease of incident light intensity.
