Optical Linear Encoders
A linear encoder is a sensor or transducer paired with a scale that encodes position. Optical technologies include shadow, self-imaging and interferometric. The main function of laser encoder is to obtain measurements. Optical linear encoders are the most widely used type of optical linear encoders because of their accuracy. Optical encoders employ shuttering/Moiré, diffraction or holographic principles. Linear encoders are usually split into two fields; incremental and absolute. Incremental optical linear encoders work by measuring pulses, while absolute encoders work to assign a one-off digital value to each position. This allows optical encoders to maintain a very precise position information, even in the event of power failure. Optical linear encoders are used in the fields of aerospace, metrology, automotive, electronics, industrial or medical applications.
