Optical encoders are the most accurate of the standard styles of encoders, and the most commonly used in industrial automation applications. When specifying an optical encoder, it's important that the encoder have extra protection built in to prevent contamination from dust, vibration and other conditions common to industrial environments.
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). [1] He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical ...
Two optical sensors (phototransistors or photodiodes) are placed very close to each other to make a linear incremental encoder. When the machine axis moves, the dark marks move under the optical encoders triggering them in succession. If movement is from, for example, left to right, encoder A is triggered first and encoder B afterwards.
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
An LED reader scans the timecode data from the film and sends it to the DTS processor, using the time code to synchronize the projected image with the DTS soundtrack audio. The multi-channel DTS audio is recorded in compressed form on standard CD-ROM media at a bitrate of 882 kbit/s. The audio compression used in the theatrical DTS system ...
The IBM 1231 is an online optical mark reader that can read and score 2000 test answer sheets per hour, depending on downstream operations. [ 6 ] The correct answers for the test can either be entered using a master sheet (like the 1230) or sent to the 1231 using the optional master-mark special feature.

The first one ("encoder") takes in image patches with positional encoding, and outputs vectors representing each patch. The second one (called "decoder", even though it is still an encoder-only Transformer) takes in vectors with positional encoding and outputs image patches again. During training, both the encoder and the decoder ViTs are used.
