Title:
ABSOLUTE OPTICAL ENCODERS USING PROGRAMMABLE PHOTODETECTOR ARRAY
Document Type and Number:
WIPO Patent Application WO/2019/139909
Kind Code:
A1
Abstract:
An encoder system includes a group of programmable detectors, a group of programmable channels, and a programmable connectivity network coupled between the programmable detectors and the programmable channels. Each of the programmable detectors is operable to produce an electric current in response to an optical or magnetic input. Each of the programmable channels is operable to produce an output in response to an electric current input. The outputs from the programmable channels form at least a part of a code word for determining an absolute position of a motion object. The programmable connectivity network is operable to route electric currents from at least a part of the programmable detectors to each of the programmable channels.
