Abstract
An optical sensing device including a base, a light sensing element, an image capturing lens, at least one light source, and a top cover is provided. The light sensing element is disposed on the base. The image capturing lens is disposed above the light sensing element. The light source is disposed on the base, beside the light sensing element, and configured to emit a light beam. The top cover covers the light source and has a slit pattern. The slit pattern includes at least one slit. The slit pattern is disposed on a path of the light beam to diffract the light beam. The image capturing lens is configured to collect a signal light formed by an outside object reflecting a diffracted light beam and transmit the signal light to the light sensing element.
