Abstract

A miniature, resonant, fiber-optic scanner driven by silicon detector photocurrent requires only 23μW to sequentially address each channel of a ten-bit optical encoder mask. The digital position code is transmitted twice each cycle to a remote readout, constituting a passive optical sensor, with multiplexing capability via its precise resonant frequency.
