Abstract

This invention relates to a displacement sensing system of an optical input device, which includes a print circuit board, a lighting device, a first light-sensing array, a second light-sensing array, a lens, and a microcontroller. Using the aforementioned structure of displacement sensing system, we can save the expensive CMOS sensor and the image process thereof, to reduce the production cost. This invention also presents a displacement sensing method of an optical input device.
