WebAn absolute optical encoder has several tracks, with different patterns on each, to produce a binary code output that is unique for each encoded position. There is a track for each output bit, so an 8-bit absolute encoder has 8 tracks, 8 outputs and 256 output combinations, for a resolution of 360/256 = 1.4°. WebOct 1, 2016 · Rotary displacement is frequently measured by optical or magnetic encoders. These are absolute or incremental, both with their particular advantages and disadvantages. Figure 3 illustrates a simple 3-bit absolute encoder. The black segments stand for “1” and the white ones for “0.” They are usually read by optical means.
