Theory of Operation
TheHEDS-9700isaC-shapedemitter/detectormodule.
Coupled with a codewheel, it translates rotary motion
into a two-channel digital output. Coupled with a
codestrip, it translates linear motion into a digital
output.
As seen in the block diagram, the module contains a
singleLightEmittingDiode(LED)asitslightsource.The
light is collimated into a parallel beam by means of a
single lens located directly over the LED. Opposite the
emitteristheintegrateddetectorcircuit.ThisICconsists
of multiple sets of photodetectors and the signal
processing circuitry necessary to produce the digital
waveforms.
The codewheel/codestrip moves between the emitter
anddetector,causingthelightbeamtobeinterrupted
by the pattern of spaces and bars on the codewheel/
codestrip.Thephotodiodeswhichdetecttheseinterrup-
tionsarearrangedinapatternthatcorrespondstothe
