Digitally Enhanced Interferometry for Precision Metrology

Bandutunga, Chathura


In this thesis we employ Digitally Enhanced Interferometric techniques to manage, measure or reject spurious interference. The technique, by using digitally controlled spread-spectrum modulation, manipulates the coherence of an optical source, enabling selective decoding of optical fields based on time-of-flight. Through this thesis, we demonstrate the use of this technique across three scenarios. Firstly, in Part 1, we consider the application to quasi-distributed interferometric sensing in...[Show more]
