One Cycle (C): 360ꢀelectricalꢀdegreesꢀ(°e),ꢀ1ꢀbarꢀandꢀwin-

Asꢀ seenꢀ inꢀ theꢀ Figureꢀ 1,ꢀ theꢀ moduleꢀ containsꢀ aꢀ singleꢀ
LightꢀEmittingꢀDiodeꢀ(LED)ꢀasꢀitsꢀlightꢀsource.ꢀTheꢀlightꢀisꢀ
collimatedꢀintoꢀparallelꢀbeamꢀbyꢀmeansꢀofꢀaꢀsingleꢀlensꢀ
locatedꢀdirectlyꢀoverꢀtheꢀLED.ꢀOppositeꢀtheꢀemitterꢀareꢀ

Pulse Width(P): Theꢀnumberꢀofꢀelectricalꢀdegreeꢀthatꢀanꢀ

180°ꢀeꢀorꢀ1¤2ꢀcycle.
ThisꢀICꢀconsistsꢀofꢀmultipleꢀsetsꢀofꢀphotodetectorsꢀandꢀ
aꢀ signalꢀ processingꢀ circuitryꢀ necessaryꢀ toꢀ produceꢀ theꢀ

andꢀdetector,ꢀcausingꢀtheꢀlightꢀbeamꢀtoꢀbeꢀinterruptedꢀ
byꢀ theꢀ patternꢀ ofꢀ spacesꢀ andꢀ barsꢀ onꢀ theꢀ codewheel/
