Abstract
A description is given of a novel light-to-frequency converter circuit which makes possible a very simple digital light meter using conventional frequency counting techniques. This circuit combines the principle of time-integration, the high stability of reverse biased silicon planar photodiodes, and first order dark current compensation to yield a potentially 0.1 percent accuracy light meter. Some discussion of temperature effects upon planar diode photocurrent is given.
