Agilent ADNS-6030
Laser Mouse Sensor
Theory of Operation
The ADNS-6030 is based on
LaserStream
Technology,
which measures changes in
position by optically acquiring
sequential surface images
(frames) and mathematically
determining the direction and
magnitude of movement.
The ADNS-6030 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.
