WebSep 15, 2014 · Optical Encoders. An optical encoder consists of a disk that passes between a light source and a photodetector (see figure 1). The disk is typically attached to the load while the source and detector remain fixed as part of the encoder body. Patterned in a series of opaque and transparent regions, the disk modulates the input beam as it turns. WebDuring the sensor placement process, the placement system measures image center, rotation, tilt and back focal distance, actively adjusting the sensor position based on feedback from visual measurements. The system employs an automated 6 degrees of freedom (6DoF) mechanical unit and a visual inspection unit.
