SMD-01 Optical Encoder Head OVERVIEW The SMD-01 is a high-precision optical encoder that employs a diffraction image projection method. It incorporates an OEIC (Opto-Electric Integrated Circuit) and LED light source in a single package. Light emitted from the LED is projected onto a scale, and the reﬂected diffraction image is focused on a photodiode. The reﬂected light contains position information that is recovered to detect the relative movement between the SMD-01 and the scale. In addition,.
