Edge filter enhanced self-mixing interferometry: an approach to access the FM self-mixing signal
Edge filter enhanced self-mixing interferometry: an approach to access the FM self-mixing signal
- Latin America Optics and Photonics Conference. Medellin Colombia 22-26 August 2016, 2016 .
We describe a new self-mixing interferometer enable to measure frequency modulation (FM)signal. The FM detection, based on FM to intensity modulation mapping, yields about two orders of magnitude larger SNR than conventional self-mixing interferometry.
