Abstract
An angle sensor for detecting the angular position of a rotating body. The angle sensor includes a plurality of digital patterns positioned on a surface that rotates with a rotating body. A source of light illuminates the patterns, and a multi-pixel optical device receives light from the patterns and converts the light into electrical signals. A processing circuit receives the electrical signals and identifies the illuminated patterns.
