The Leviton absolute optical encoder is an ultra-precise position-measuring device, capable of detecting linear and angular displacements as small as 1 nm and 0.006 arc seconds, respectively. We developed the first encoder design that produces position updates using the National Semiconductor LM9637 CMOS active pixel sensor, a FPGA, and a DSP. We also proved that just a FPGA could be used with the sensor to achieve even faster results, thus, reducing the overall cost and complexity of the Leviton Encoder.
