About this document
Understanding Optical Encoders by Pratik Kalantre is a document available to read on EtoBox.
The document discusses an optical encoder which converts rotational motion into an electrical signal. It consists of a light emitting diode (LED) and photo transistors that detect light passing through a slotted disk. As the disk rotates, the photo transistors output a sine wave that is converted to a square wave. The number of lines on the disk determine the pulses per revolution which can be used to measure revolutions per minute using LabVIEW.
