摘要： A self-calibrating optical feedback system for an optical navigation device. The self-calibrating optical feedback system includes a light source, an illumination lens, a beam splitter, and an optical feedback device. The illumination lens is coupled relative to the light source. The light source emits light based on a programming current. The illumination lens directs the light towards a beam splitter. The beam splitter partially reflects the light directed from the illumination lens. The optical feedback device detects the partially reflected light from the beam splitter and generates a feedback signal to modify an intensity of the light emitted by the light source. Embodiments of the self-calibrating optical feedback system maintain the output intensity of a laser driven optical navigation device below an eye-safety level.

摘要： A dual-channel optical navigation system with vertically aligned sensors. The dual-channel optical navigation system includes a circuit board, a contact navigation sensor, and a free-space navigation sensor. The circuit board mechanically supports and electrically connects multiple navigation sensors on opposing sides of the circuit board. The contact navigation sensor is coupled to a first side of the circuit board. The contact navigation sensor generates a contact navigation signal based on contact navigation images of a contact navigation surface approximately adjacent to the dual-channel optical navigation system. The free-space navigation sensor is coupled to a second side of the circuit board. The free-space navigation sensor generates a free-space navigation signal based on free-space navigation images of an operating environment of the dual-channel optical navigation system.

摘要： A light pipe for an optical navigation system. The light pipe includes a collection surface, a collimation surface, and a reflective surface. The collection surface is to accept incident light into the light pipe from a light source. The collimation surface is to collimate the light and to direct the collimated light to a navigation plane for detection by a navigation sensor. The reflective surface is between the collection surface and the collimation surface and is to reflect the light along a reflective path as the light travels within the light pipe from the collection surface to the collimation surface. The reflective surface has a curved geometry oriented substantially along the path of travel of the light through the light pipe. The curved geometry of the reflective path facilitates convergence of the light with respect to a first axis.
