Theory of Operation
The ADNS-3000 is based on Optical Navigation Technol-
ogy, which measures changes in position by optically
acquiring sequential surface images (frames) and math-
ematically determining the direction and magnitude of
movement.
The ADNS-3000 contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a four 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 dis-
placement values
An external microcontroller reads and translates the Dx
and Dy informa tion from the sensor serial port into PS2,
USB, or RF signals before sending them to the host PC.
