Abstract
A light source emits modulation light and irradiates a measured object with the modulation light, and a measurer receives modulated detection light obtained from the measured object. Charge is accumulated with respect to a relative exposure timing in the measurer according to the modulated detection light. Using a variation profile of charge accumulation values respectively relating to the relative exposure timings, a system controller calculates distance to the measured object.
