    摘要： An optical pointing device includes a light source configured to respond to a drive current to provide at least partially coherent light to illuminate an imaging surface to thereby generate reflected images. A navigation sensor is configured to generate digital images based on the reflected images, and generate movement data based on the digital images that is indicative of relative motion between the imaging surface and the optical pointing device. A light source driver is configured to provide the drive current to the light source. A drive current controller is configured to calibrate the drive current based on selected digital images.

    摘要： A contaminant-neutralizing cradle comprises a base and a support surface configured to removably receive a coherently-illuminated mouse. A neutralizing element is disposed on the support surface for alignment with at least one exposed surface of an optics module of the mouse and is configured to neutralize the optical effect of a contaminant on the at least one exposed surface. A method of neutralizing contaminants for an optical mouse comprises providing a mouse containing an optics module having at least one surface exposed to an opening of the mouse and interposing a barrier in the mouse between a contaminant and the at least one exposed surface. A method of detecting contaminants comprises aligning an optics module of a mouse with an imaging surface, obtaining a first image of the imaging surface, via application of coherent illumination from the optics module to the imaging surface, analyzing the first image to identify an interference pattern associated with a contaminant, alerting a user if a parameter of the interference pattern exceeds a threshold value.
