Abstract:
An optical mouse operated with respect to an illuminated surface outside the optical mouse is provided. The optical mouse includes a light source configured to emit a light beam, and a light pipe including a first optical element and a second optical element. The light beam enters the light pipe through the first optical element, and then propagates in the light pipe from the first optical element to the second optical element without reflection, and then leaves the light pipe through the second optical element, and then illuminates the illuminated surface. The light pipe does not have any protrusion extending therefrom and attached to a front surface of the light source.
Abstract:
There is provided an illumination system of a navigation device including a light beam shaping optics, and a first light source and a second light source having different characteristics. The light beam shaping optics is used to shape light beams emitted by the first light source and the second light source to illuminate a work surface with substantially identical incident angles and/or beam sizes.
Abstract:
There is provided an optical navigation module including an optical package and a light reflective element. The optical package includes an image sensor which has a sensor surface. The light reflective element is configured to reflect light propagating parallel to the sensor surface to light propagating perpendicular to the sensor surface to impinge on the sensor surface thereby performing the lateral detection.

Abstract:
There is provided a lens piece and a lens assembly as well as an imaging device including the same. The lens assembly includes the lens piece and a lens barrel. The lens piece has a wing extending transversely from a lens sidewall. The lens barrel carries the lens piece, and includes a reservoir corresponding to the wing of the lens piece for containing adhesive.
Abstract:
There is provided an image module package including a substrate, a photo sensor chip, a molded transparent layer and a glass filter. The substrate has an upper surface. The photo sensor chip is attached to the upper surface of the substrate and electrically connected to the substrate. The molded transparent layer covers the photo sensor chip and a part of the upper surface of the substrate, wherein a top surface of the molded transparent layer is formed with a receptacle opposite to the photo sensor chip. The glass filter is accommodated in the receptacle.
Abstract:
There is provided a mode switching method of a dual mode optical navigation device. The dual mode optical navigation device is configured to be operated on a working surface and has a first bottom surface and a second bottom surface having an included angle with the first bottom surface. The mode switching method includes: determining whether the first bottom surface or the second bottom surface contacts with the working surface; switching the dual mode optical navigation device to a first mode when identifying that the first bottom surface contacts with the working surface; and switching the dual mode optical navigation device to a second mode when identifying that the second bottom surface contacts with the working surface.
