Theory of Operation

The ADNS-3040 is based on Optical Navigation Technology, which measures changes in position by optically acquiring sequential surface images frames and mathematically determining the direction and magnitude of movement.

The ADNS-3040 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 'x and 'y relative displacement values.

An external microcontroller reads the 'x and 'y information from the sensor serial port. The microcontroller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console.
