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.
