Abstract

An optical sensing device is used to sense a relative moving object. The optical sensing device includes an optical sensing element and a signal-processing unit. The optical sensing element is used to sense the movement of an object and outputs a sensing signal according to a modulating signal. The signal-processing unit couples to the optical sensing element and processes the sensing signal to output a first data signal and a second data signal. The frequency of the first data signal lies in a first band of the sensing signal and the frequency of the second data signal lies in a second band of the sensing signal. The first band differs from the second band.
