摘要： A compact and miniature optical navigation device integrates an illumination channel and an imaging channel into single piece. The present invention integrates the optical system, the mechanical system, and the electrical system into a small form factor device. The compact and miniature optical navigation device includes a photo-imaging element, a housing, and a first substrate. The photo-imaging element comprises an imaging channel and an illumination channel. The housing includes an aperture stop and an alignment element. The aperture stop and the housing are integrated into one piece and the alignment element is part of the housing. The first substrate includes a light source and a sensor. The light source and the sensor are located on the same surface of the first substrate. The light emitted from the light source passes through the illumination channel, reflected from the navigating surface and forms the image on the sensor.

摘要： An optical tracking assembly for an optical mouse includes a light source, an optical sensor chip, and an integral optics assembly. The integral optics assembly includes lenses and alignment features receiving the light source. The alignment features center the light source to the lenses and control a distance the light source is placed away from a navigation surface that reflects light onto the optical sensor chip. The lenses may include (1) collimating lenses for collimating light from the light source along a first optical axis to the navigation surface, and (2) imaging lenses for imaging reflected light from the navigation surface along a second optical axis to the optical sensor chip.
