Abstract
An optical sensing module includes an image sensing element having an optical sensor array and at least a control unit. A light emitting chip provides a coherent light. The light is reflected from an outside surface and to be received by the optical sensor array. A substrate is mounted with the image sensing element and the light emitting chip. A cover is mounted on the substrate to cover the image sensing element and the light emitting chip, and the cover includes a first light-transmitting portion on the transmission path of the light. The optical sensing module is disposed on a base having a second light-transmitting portion on the transmission path of the light.
