摘要： An optical scrolling module includes a prism, a light source, an image sensor and a first condenser. The prism is disposed at an opening of an upper shell of a mouse and has a light incident surface, a reflective surface, a contact surface and a light emitting surface. The contact and light incident surfaces are respectively connected between the reflective and light emitting surfaces. The contact surface is exposed by the opening. A light beam from the light source is transmitted to the contact surface via the light incident and reflective surfaces. When an object with a pattern structure puts on the contact surface, the light beam is scattered and a portion of the light beam is transmitted to the image sensor via the first condenser. When the object is removed from the contact surface, the light beam is reflected to the light emitting surface by the contact surface.

摘要： An optical pointing device includes an illumination system, an imaging system and at least one diffraction element. The illumination system includes a light source for providing a light beam to a reflective surface outside the optical pointing device. The imaging system includes an image sensor disposed on a transmission path of the light beam after being reflected by the reflective surface. The at least one diffraction element is disposed in the illumination system and/or the imaging system and disposed on the transmission path of the light beam to change the transmission path of the light beam. The present optical pointing device can achieve the advantage of small volume.

摘要： A lens module is suitable for a wafer level process and works in collaboration with an image sensor. The lens module includes a substrate, a lens and a spacer. The lens is disposed on a surface of the substrate for concentrating a light. The spacer is disposed on the substrate and surrounds the lens to block the light from penetrating the substrate through a circumference of the lens. The substrate and the lens are made of a light transmissive material and the spacer is made of an opaque material for shielding a stray light coming from outside, thereby improving a sensing performance of the image sensor.
