Balanced detection for self-mixing interferometry [PDF]
Optics Letters, 2017 We propose a new detection scheme for self-mixing interferometry using two photodiodes for implementing a differential acquisition. The method is based on the phase opposition of the self-mixing signal measured between the two laser diode facet outputs.

Self-mixing interferometry and its applications
SPIE Proceedings, 2016 This paper reviews the self-mixing interference (SMI) in terms of its operation principle, the features of SMI signals and its configuration. SMI refers to a phenomenon that occurs when a small fraction of the light emitted by a laser is backscattered or reflected by an external target and re-enters the laser active cavity, thus leading to the ...

Self-mixing interferometry used for instrumentations and measurements(invited)
Chinese Journal of Optics and Applied Optics, 2012 This paper reviews the development of a new configuration of interferometry, Self-mixing Interferometry(SMI). SMI is attractive because it doesn't require any optical part external to the laser and can be employed in a variety of measurements, ranging from the traditional measurements related to optical path length like displacements, small-amplitude ...

Feedback Regimes of LFI Sensors: Experimental Investigations
Sensors, 2022 In this article, we revisit the concept of optical feedback regimes in diode lasers and explore each regime experimentally from a somewhat unconventional point of view by relating the feedback regimes to the laser bias current and its optical feedback ...

Distance Measurement with Harmonic Modulation of Self-Mixing Laser Wavelength at External Optical Feedback [PDF]
Известия Саратовского университета. Новая серия: Физика, 2020 Background and Objectives: Self-mixing interferometry of absolute distances is currently well represented by the method of frequency modulation of the laser diode supply current (FMCW). In recent years a harmonic modulation of the power current of a self-
