摘要： A user input device to generate an optical navigation signal based on an edge-lit pattern. The user input device includes an optical element, a light source, a sensor array, and a navigation engine. The optical element includes a finger interface surface. At least a portion of the optical element exhibits total internal reflection (TIR). The light source provides light to the finger interface surface. The sensor array detects light reflected from the finger interface surface in response to contact between a finger and the finger interface surface. The contact between the finger and the finger interface surface disrupts the TIR and causes light to be reflected out of the optical element towards the sensor array. The navigation engine generates lateral movement information, which is indicative of lateral movement of the finger relative to the sensor array, in response to the detected light.

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： An Optical Projecting Encoder (“OPE”) having an emitter module for transmitting emitted optical radiation through a mask to a moving object, and a detector module for receiving reflected optical radiation from the moving object. The reflected optical radiation from the moving object may include a predetermined image cast by the mask and a surface texture image from the moving object. The OPE may include a transmissive layer covering both the emitter module and the detector module, where the transmissive layer covering the emitter module collimates the optical radiation from the emitter module, and the transmissive layer covering the detector module concentrates the optical radiation reflected from the moving object to the detector module. The detector module may include an optical navigation sensor that continuously acquires and compares predetermined images cast by the mask and surface texture images from the moving object.
