Laser Mouse Sensor
Data Sheet
Theory of Operation
The ADNS-7050 is based on LaserStream™ Technology,
which measures changes in position by optically acquir-
ing sequential surface images (frames) and mathemati-
cally determining the direction and magnitude of move-
ment.
The ADNS-7050 contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a four wire se-
rial 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.
