International audience; The fringes disappearance phenomenon in the self-mixing interferometry occurs whenever the external round-trip phase at free-running state is modulated by either external modulation such as external cavity length changes or in

International audience; Absolute distance measurement by means of a self-mixing interferometer (SMI) can be obtained by modulating the laser frequency. This modulation is typically achieved through the modulation of the laser injection current with a

Adaptive Transition Detection Algorithm for a Self-Mixing Displacement Sensor

Autor: Francis Bony, Usman Zabit, Thierry Bosch

Publikováno v: IEEE Sensors Journal. 9:1879-1886

A new algorithm for self-mixing (SM) sensors has been developed to perform displacement measurements. It is able to differentiate between the different SM regimes (very weak, weak, moderate, and strong) and thus converges automatically to the optimum

Publikováno v: IEEE Sensors Conference
IEEE Sensors Conference, Nov 2014, Valencia, Spain

International audience; This paper presents a robust phase estimation to detect fringes of self-mixing signals for all feedback levels. It aims to avoid the need of restricting a particular working feedback regime for a sensor which is usually done b
