Reflective Optical Encoders
Jul 2014
Broadcom Ltd.
SAN JOSE, Calif., July 28, 2014 — With an encoding resolution of up to 318 lines per inch, the AEDR-87 series of reflective optical encoders from Avago Technologies is packaged in a small form factor for a three-channel device.

The encoders support 3.3-V and 5-V supply voltage for low-power applications. Dual analog/digital outputs interface directly with an external interpolator for high-precision motion control measurements.

The devices can be used in low-power miniaturized motion control systems such as stepper motors, electrical actuators, piezoelectric drives and portable medical appliances.

A physical variable that is proportionally similar to another variable over a specified range. An analog recording contains data that is similar to the source.
Denoting the use of binary notation; i.e., the representation of data by bits (1 or 0).
The hardware for reading (and writing in devices so equipped) an optical mass data storage disk.
Pertaining to optics and the phenomena of light.
1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
A combination of components arranged so as to perform at least one function.
