PMW3610DM-SUDU
Low Power Laser Mouse Sensor
Description
The PMW3610DM-SUDU integrated molded lead-frame DIP laser
sensor comprises of sensor and VCSEL in a single package.
PMW3610DM-SUDU provides enhanced features such as
programmable resolution, configurable sleep and wake up time to suit
various wireless optical navigation applications.
The advanced class of VCSEL was engineered by PixArt to provide
a laser diode with a single longitudinal and a single transverse mode.
The laser sensor is packaged into a 16-pin integrated molded lead-
frame (DIP) package. It is designed to be used with LM18-LSI lens
to achieve the optimum performance. Together these parts provide
a complete and compact navigation system without moving parts.
Laser calibration process is NOT required; it is pre-calibrated at
sensor level which helps to facilitate high volume assembly.
Theory of Operation
The sensor is based on PixArt Laser Technology, which measures
changes in position by optically acquiring sequential surface images
(frames) and mathematically determines the direction and
magnitude of movement. It contains an Image Acquisition System
(IAS), a Digital Signal Processor (DSP), and a three 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 Δx and Δy relative displacement values. An external
microcontroller reads the Δx and Δy information from the sensor
serial port. The microcontroller then translates the data into USB or
RF signals before sending them to the host PC or game console.
