The sensor is configured with a depth of field to support a distance between the sensor and the reflective surface. A contact sensor is also included to indicate when the optical navigation device is no longer in contact with the transparent layer. The contact sensor allows for skating functionality for the optical navigation device.

摘要： Multiple images of an object are captured by one or more imagers. Each image is captured with one or more differing image capture parameters. Image capture parameters include the status (i.e., on or off), wavelength and position of each light source and the status and position of each imager. Two or more difference images are then generated using at least a portion of the captured images and the difference images analyzed to detect the object. The reflections from artifacts are reduced or largely cancelled out in the difference images when each image is captured with one or more different image capture parameters.
摘要翻译：对象的多个图像由一个或多个成像器捕获。每个图像都被一个或多个不同的图像捕获参数捕获。图像拍摄参数包括每个光源的状态（即，开或关），波长和位置以及每个成像器的状态和位置。然后使用所捕获图像的至少一部分和分析的差分图像来生成两个或更多个差异图像以检测对象。当使用一个或多个不同的图像捕获参数捕获每个图像时，差异图像中的伪影的反射被减少或很大程度地抵消。

摘要： An improved optical switch allows for the testing, calibration and monitoring of optical switch points in an optical switching matrix. A test column and a test row of additional switch elements and optical paths enable the improved optical switch to provide testing, calibration and monitoring of each optical switch point in the optical switch matrix using a test input source and a test output receiver. The improved optical switch may also be used to test for the presence of light at any input and to inject a test signal into the matrix in order to test for the presence and quality of light at any output.

摘要： An apparatus and method for measuring the thickness of a film having top and bottom surfaces. The apparatus includes low coherence light source that generates a probe light signal. The film is positioned between first and second reference reflectors, the first reference reflector being partially reflecting. The probe light signal is applied to the film after passing through the first reference reflector. Part of the portion of the probe light signal leaving the film is reflected back toward the first reference reflector by the second reference reflector. The light exiting through the first reference reflector is collected to form the input to a receiver that determines the time delay between light reflected from the top and bottom surfaces of the film as well as the change in optical path length between said first and second reflectors resulting from the introduction of said film between said first and second reflectors. In the preferred embodiment of the present invention, the receiver is constructed from an optical autocorrelator or an optical spectrum analyzer that includes circuitry for providing the Fourier transform of the frequency domain spectrum measured from the combined light signal. Embodiments in which only one of the reference reflectors is utilized provide a means for simplifying the output spectrum from the receiver when multi-layer films are utilized.

摘要： An apparatus and method for measuring the thickness of a film. The film is illuminated with a low coherence light signal that is preferably generated from a source including two or more LEDs. The light reflected from the surfaces of the film is collected and coupled to an interferometer. The slope of the Fourier transform of the output of the signal from the interferometer is measured to provide a determination of the thickness of the film. In the preferred embodiment of the present invention, the interferometer output is sampled at fewer than two points per cycle of the low coherence light signal.
