Abstract
A circuit measures the intensity of a monitored light beam by generating a signal which is of a specific time duration corresponding to light intensity. The circuit utilizes a photosensitive element for receiving the light and producing a variable control signal in direct correspondence to the light intensity. A capacitor network is placed in series with the photosensitive element, wherein the time duration for discharging the capacitor network is directly correlated to the intensity of the collected light.
