Abstract: An optical pointing device for detecting the direction of the user's finger is provided. The optical pointing device comprises a cover, a light source and a sensor. The cover comprises a press portion with a first surface and a second surface opposite the first surface, as well as a side wall extending downwards from the periphery of the second surface. The light source projects a main beam onto the press portion of the cover. The main beam then forms a first beam passing through the press portion and a second beam reflected by the second surface. The sensor is adapted to receive the second beam reflected by the second surface, and detect the second beam by an algorithm to output the first displacement position. In addition, the light source and the sensor are covered by the cover, while the side wall is a flexible side wall.

Abstract: There is provided an optical engine for a navigation device including a first light source, a second light source, a lens, a carrier member and an image sensor. The carrier member has a light holder, a lens holder, an accommodation space and a tilted wall. The first light source is arranged on the light holder of the carrier member, and reflected light associated with the first light source penetrates through the lens to propagate to the image sensor inside the accommodation space. Reflected light associated with the second light source penetrates through the tilted wall of the carrier member to propagate to the image sensor.

Abstract: There is provided a bottom cover for being covered on an optical system. The bottom cover is attached in front of the optical engine. The bottom cover has a bottom surface for facing a working surface when the optical system is moving on the working surface, a first opening for emission light of the optical engine to go through and a second opening for reflected light from the working surface to go through. The bottom cover is further formed with guiding protrusions protruded out from the bottom surface toward the working surface and surrounding at least the second opening to guide soft materials on the working surface to away from the second opening.

Abstract: There is provided a miniaturized optical system including a protection cover, a light source, an image sensor and at least one interference film. The protection cover has a first surface and a second surface. The light source and the image sensor are disposed opposite to the first surface of the protection cover. The interference film is disposed between the light source and the protection cover to allow the light source to form a predetermined light shape in front of the second surface of the protection cover and/or disposed between the image sensor and the protection cover to allow the image sensor to receive light of a predetermined range in front of the second surface of the protection cover.
