摘要:
An optical navigation system having two or more optical pipelines for image acquisition and a single multiplexed optical array. Each of the two or more optical pipelines for image acquisition may include an illuminator that emits optical radiation at a navigation surface where each navigation surface is separate from the other navigation surfaces. The single multiplexed optical array may be configured to receive optical radiation reflected from the respective navigation surfaces. The optical navigation system may further include illuminator drivers that control each of the optical pipelines for image acquisition and an optical sensor that is configured to multiplex the images recovered by the optical pipelines for image acquisition and perform image correlation for the different navigation surfaces.

An optical computer mouse has a support structure that can be moved across a surface. An illumination source that illuminates a region of the surface is coupled to the support structure. An imaging system in the mouse includes an optical sensor array that receives light from the illuminated region of the work surface and an image processor that receives data from the optical sensor array. The optical computer mouse may be switched between a navigation mode of operation, in which the image processor detects motion of the optical computer mouse over the work surface, and a barcode reading mode of operation, in which the image processor senses a barcode as the optical computer mouse is moved across a barcode.

An optical encoding apparatus for the detection of position and/or motion of a mechanical device includes a codescale, an encoder housing having one or more portions and a light-detecting sensor embedded within the encoder housing, wherein the light-detecting sensor is capable of sensing a pattern produced by the codescale superimposed on the light-detecting sensor, and wherein the light-detecting sensor includes a two-dimensional array of light detection elements having dimensions n-by-m where n and m are both integers greater than 4.

An optical navigation apparatus and method for making the apparatus uses a light source and a sensor having an imaging array mounted on a leadframe and encapsulated in an optically transparent body structure. The optically transparent body structure is configured to include a prism-like feature to internally reflect light from the light source toward a target surface and an imaging lens feature to optically manipulate the light reflected from the target surface onto the imaging array of the sensor.

An optical navigation device, such an optical mouse, includes a housing, an illumination system, a tracking engine, and multiple height-specific imaging systems located within the housing. The height-specific imaging systems generate image information in response to reflected light from a navigation surface and each one the height-specific imaging systems is positioned to detect the largest portion of reflected light at a different separation distance between the housing and the navigation surface. An integrated circuit (IC) device for optical navigation includes an aperture plate having height-specific apertures and height-specific navigation sensor arrays aligned in one-to-one correspondence with the height-specific apertures and configured to generate image information in response to light that passes through the corresponding height-specific apertures. An optical element for use in an optical navigation system includes an illumination source lens and multiple height-specific focal lenses.

An optical navigation system having an illuminator housing and a sensor housing that are movably connected at a connection point with a connection mechanism, which may include a pivot. The illuminator housing and the sensor housing may be rotated about the connection point relative to each other so that the optical navigation system may be configured with a desired operating Z-height. The optical navigation system may also include a locking mechanism to lock the illuminator housing and the sensor housing in a predetermined fixed position after the desired operating Z-height has been selected.

A pointing device and method for using the same to measure the motion of that pointing device over a surface is disclosed. The pointing device includes an illumination system, an imaging system, and a controller. The illumination system generates light in a plurality of wavelength bands and illuminates a surface below the pointing device with light from one of the wavelength bands. The imaging system records images of the illuminated surface. The controller selects the wavelength band used to illuminate the surface, compares first and second images recorded by the imaging system at different times when the surface is illuminated with that wavelength band, and determines a displacement indicative of the direction and distance the positioning device moved between the two different times.
