A New Architecture for Absolute Optical Encoders

摘要

BEI Precision Systems & Space has developed an encoder technology, nanoSeries, that can calibrate itselfrnin-situ and correct most of the common causes of error in typical encoders. The new nanoSeries ARArndesign has detailed health and status readouts that can definitively indicate when a re-calibration is in order.rnThe re-calibration process can be done on-orbit if desired. The units can accommodate either fullrnrevolutions or limited angle sweeps, and the principles are also applicable to linear encoders.
