摘要： A pointing device and method for using the same are disclosed. The pointing device includes an illumination system, an imaging system, and a controller. The illumination system illuminates a portion of a surface over which the pointing device travels with coherent light. The imaging system includes a first window for receiving light from the illuminated portion of the surface and transmitting that light to a first imaging array such that a speckle pattern is generated on the first imaging array and a second window includes an imaging optical system for forming an image of part of the illuminated portion of the surface on a second imaging array. The controller selects either the first imaging array or the second imaging array and compares the output of the selected imaging array at first and second times to determine a displacement indicative of the direction and distance the pointing device moved.

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.

摘要： An apparatus having a coherent light source, an optical sensor, and a controller that can be utilized in optical mice and the like is disclosed. The coherent light source emits coherent light in a cone of angles about an illumination direction. The optical sensor includes an array of photodetectors disposed on a die having a surface substantially perpendicular to the illumination direction. The controller compares first and second images recorded by the optical sensor at different times and determines a displacement indicative of the direction and distance the apparatus has moved between the two different times. A portion of the coherent light source is bonded to the die at a location within the array of photodetectors.

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.
