Abstract: Abstract In this paper, an enhanced laser self-mixing interferometry based on tunable Fabry-Perot Filter is proposed. The frequency-modulated (FM) self-mixing signal is transformed into intensity variations by a Fabry-Perot Filter, which transforms laser frequency variations… read more here.
