Description
The ADNS-2051 is a low cost
optical sensor used to implement a
non-mechanical tracking engine for
computer mice.
It is based on optical navigation
technology, which measures
changes in position by optically
acquiring sequential surface images
(frames) and mathematically deter-
mining the direction and magnitude
of movement.
The sensor is housed in a 16-pin
staggered dual inline package (DIP)
that is designed for use with the
HDNS-2100 Lens and HDNS-2200
Clip and HLMP-ED80-XXXXX
(639 nm LED illuminator source).
There are no moving parts, and
precision optical alignment is not
required, facilitating high volume
assembly.
The output format is two channel
quadrature (X and Y direction)
which emulates encoder photo-
transistors. The current X and Y
information are also available in
registers accessed via a serial port.
Default resolution is specified as
400 counts per inch (cpi), with
rates of motion up to 14 inches
per second (ips).
Resolution can also be pro-
grammed to 800 cpi.
The part is programmed via a two
wire serial port, through registers.
Theory of Operation
The ADNS-2051 is based on
Optical Navigation Technology.
It contains an Image Acquisition
System (IAS), a Digital Signal
Processor (DSP), a two-channel
quadrature output, and a two wire
serial port.
The IAS acquires microscopic
surface images via the lens and
illumination system provided by
the HDNS-2100, 2200, and
HLMP-ED80-XXXXX LED. These
images are processed by the DSP
to determine the direction and
distance of motion. The DSP
generates the
x and
y relative
displacement values that are
converted into two channel
quadrature signals.
