    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.

    摘要： The various embodiments generally describe systems and methods related to 3-dimensional (3-D) imaging. In one exemplary embodiment, an imaging system incorporates a 2-dimensional (2-D) image capture system that generates 2-D digital image information representing an object, a signal transmitter that transmits a ranging signal towards the object, and a signal receiver that receives the ranging signal returned by the object. Also included, is an image processor that computes distance information from the time difference between signal transmission and reception of the ranging signal. The image processor combines the distance information and 2-D digital image information to produce 3-D digital image information representing the object.

    摘要： Tracking separation between an object and a surface involves illuminating the surface and reducing the collection angle of light that reflects off of the surface in response to a change in separation between the object and the surface. Reducing the collection angle of light that reflects off of the surface causes the amount of light that is detected to be dependent on the separation distance between the object and the surface. The amount of detected light is then used as an indication of the separation distance.

    摘要： A tunable optical filter utilizes multiple electroholographic (EH) gratings with different center wavelengths to filter an optical signal over a wide wavelength range. The EH gratings are connected such that an input optical signal passes through at least one of the EH gratings. The EH gratings are activated and tuned by electrode pairs that are controlled through a voltage controller. The tunable optical filter is coarse tuned by activating the EH gratings having a wavelength range that includes the center wavelength that is to be filtered and fine tuned by adjusting the voltage that is applied across the activated EH gratings.
