Agilent HDNS-2000
Optical Mouse Sensor
Product Brief
Description
You Can Use the Mouse Wherever
You Want: Innovative Ball-less
Mouse by Agilent
The HDNS-2000 is a low cost
reflective optical sensor that
provides a non-mechanical
tracking engine for implementing
a computer mouse. It is based on
optical navigation technology
which measures changes in
position by optically acquiring
sequential surface images for 1500
times per second and mathemati-
cally determining the direction
and magnitude of movement
precisely at 400 counts per inch
and at speeds up to 12 inches per
second.
Agilent provides the complete
tracking engine kit. The CMOS
based sensor is mounted in a
plastic package and designed to be
used with the HDNS-2100 (Lens),
HDNS-2200 (LED Clip) and
HLMP-ED80 (639 nm LED illumi-
nation source).
Theory of Operation
The sensor acquires an image 1500
times a second, and compares the
most recent image to past images
to determine the direction and
speed of movement.
