Optical encoder










Image Number 11 for United States Patent #7019282.

An optical encoder includes a scale having an optical grating formed thereon, a plurality of light-receiving devices, a light-emitting device, and a position-information detecting unit. The plurality of light-receiving devices is movable with respect to the scale. The light-emitting device applies light to the plurality of light-receiving devices through the scale. A position-information detecting unit detects position information in one cycle of a two-phase signal supplied from the light-receiving device. A determining unit determines an amplitude of an analog signal based on the position information.
