Theory of Operation

The ADNS-2080 is based on Optical Navigation ogy, which measures changes in position by optically acquiring sequential surface images frames and ematically determining the direction and magnitude of movement.

The ADNS-2080 contains an Image Acquisition System IAS , a Digital Signal Processor DSP , and a two wire serial port.

The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the Dx and Dy relative placement values.

An external microcontroller reads and translates the Dx and Dy from the sensor serial port into PS2, USB, or RF signals before sending them to the host PC.
