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 image detecting apparatus includes an illumination system and a sensing system. The illumination system is for providing a light beam to a working surface to generate a reflected light beam by the working surface. The sensing system includes a sensing unit and a condensing unit. The sensing unit is disposed on a transmission path of the reflected light beam reflected by the working surface for receiving the reflected light beam. The condensing unit is disposed between the sensing unit and the working surface, wherein an optical axis of the condensing unit is deviated from a main optical axis of the reflected light beam.

摘要： According to the claimed invention, an optical pointing device includes a cover having a transparent part, and a sensing component installed inside the cover. The sensing component includes a light emitting module for emitting light, and a light sensing module for sensing light transmitted from the transparent part. The optical pointing device further includes a light guiding component installed between the sensing component and the cover. The light guiding component includes a reflecting part for reflecting the light emitted from the light emitting module to the transparent part, and a condensing part integrated with the reflecting part monolithically for condensing light transmitted from the transparent part to the light sensing module. The light emitted from the light emitting module is reflected to the transparent part by the reflecting part and then reflected back to the transparent part and the condensing part by a shelter disposed above the cover.

摘要： An optical pointing device includes a light source, a light beam splitter, an image sensor and a lens. The light source provides an illumination light beam. The light beam splitter is disposed on a transmission path of the illumination light beam and configured for splitting the illumination light beam into a first light beam and a second light beam. The image sensor is for sensing the first and the second light beams. The lens is disposed before the image sensor. When the optical pointing device is put on a reflective surface, the first light beam is reflected to the lens by the reflective surface and then is focused on the image sensor. When the optical pointing device is put on a transparent body disposed on the reflective surface, the second light beam is reflected to the lens by the reflective surface and then is focused on the image sensor.

摘要： A light source module including a light source assembly and a light converging element is provided. The light source assembly provides an illumination beam and the light converging element is disposed on a transmission path of the illumination beam. The light converging element has a top end and a bottom end opposite to the top end. The light converging element is gradually reduced from the bottom end to the top end. The top end is opposite to the light source assembly and has a cavity. The illumination beam is incident into the light converging element from the cavity and exits the light converging element from the bottom end. The illumination beam is converged by the light converging element, so the diverging angle of the illumination beam provided by the light source module is relatively small.
