Abstract

Provided are systems and methods for performing high-precision length measurement. One such system includes: an optical receiver, configure to receive a reflected optical pulse from a target; an optical combiner, configured to generate a combined optical pulse using the reflected optical pulse and a reference optical pulse; and a signal analyzer configured to determine a distance to the target using a depth of modulation value of the combined signal. A method as disclosed herein includes the steps of determining a first length component of a combined optical signal using a depth of modulation value and determining a second length component of the combined optical signal using a modulation period value.
