Encoders and resolvers 
Absolute Encoders A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position of a shaft or axle to an analog or digital code, making it an angle transducer

Digital Encoders A digital optical encoder is a device that converts motion into a sequence of digital pulses, Absolute encoder, Incremental encoder, Gray code
Digital optical encoder a digital optical encoder is a device that converts motion into a sequence of digital pulses. By counting a single bit or by decoding a set of bits, the pulses can be converted to relative or absolute position measurements. Encoders have both linear and rotary configurations, but the most common type is rotary, Gray code

Digital to Synchro/Resolver Conversion Digital to Synchro/Resolver converters are used to interface digital systems to Synchro or Resolver angular control systems, ..., pdf file
Encoder handbook Encoders are sensors that generate digital signals in response to movement. Both shaft encoders, which respond to rotation, and linear encoders, which respond to motion in a line, are available. When used in conjunction with mechanical conversion devices, such as rack-and-pinions, measuring wheels, or spindles, shaft encoders can also be used to measure linear movement, speed, and position, pdf file
Encoders an encoder is a rotary device that outputs digital pulses in response to incremental angular motion. Encoders have many uses in positioning applications. For example, a rotary encoder attached to a DC motor can be used to keep track of the number of revolutions the motor has rotated from its initial position, pdf file

Incremental Encoders
Linear and rotary encoders an encoder is an electrical mechanical device that can monitor motion or position. A typical encoder uses optical sensors to provide a series of pulses that can be translated into motion, position, or direction, encoder transducer technology, Linear and Rotary Encoders, Incremental Rotary Encoder, Absolute Encoders
