Abstract

We present a low-complexity optical ranging system intended for distance ranging to moving biological tissue. The optical ranging technique used is short tuning range, optical FMCW interferometry, in a Fabry-Perot configuration, with a common-path downlead. We demonstrate ranging to a bovine muscle tissue sample over a 250 mm range with an average resolution of 0.55 mm.
