Abstract: A light guide module is applied in an optical touch module. A focusing component of the light guide module focuses the light emitted from a light guide component of the light guide module, so that all the light emitted from the light guide component can be convergently distributed in a touch area of the optical touch module. In this way, the light provided by a lighting component of the optical touch module can be effectively utilized, and the signal to noise ratio of the received signal of a sensor of the optical touch module increases. Therefore, the optical touch module can determines the location of the finger or the contacting object more correctly.

Abstract: In a lens module and an optical mouse using the lens module, the lens module includes a substrate, a light guide rod and a carrying base. The light guide rod is extended from the substrate along a predetermined direction and has a light incident surface. The carrying base is connected with the light incident surface and has a carrying surface for carrying a light source of the optical mouse. The substrate, the light guide rod and the carrying base are integrated into one piece. The lens module has lower cost.

Abstract: An apparatus and method for fingerprint recognition comprises a light source, an optical component, an imaging device and a processor. The light source directs a monochromatic light through the optical component and then forms a plurality of interference fringes on a fingerprint desired to be recognized; the imaging device receives an optical image signal of the interference fringes reflected from the fingerprint and transfers it to an electrical image signal; the processor creates a contour image of the fingerprint according to the electrical image signal for post-recognition.
