In this chapter, we discuss the oscillation conditions for semiconductor lasers and, then,
derive the rate equations, which are the starting points of the study of chaotic dynamics in …

A review of recent experimental and theoretical results concerning laser diode self-mixing
velocimetry is presented, showing that this technique can be deployed to measure velocity …

The principle and the experimental realization of a new type of laser vibrometer based on
the self-mixing interference effect in a laser diode are presented. The self-mixing …

The spectral properties of a laser diode are modified when the optical beam is back-
scattered into the active cavity of the laser. Based on the use of this optical feedback, the self …

Optical sensors are used extensively for displacement measurement. A cost-effective optical
displacement sensor will be invaluable in applications where very high resolutions are not …

The quadrature demodulation algorithm used for all-fiber self-mixing sensors is applied to
displacement measurements. A fiber electro-optic modulator is used to introduce phase …

This paper presents recent results in the development of novel ultrafast technologies based
on the generation and application of extremely chirped optical pulses. Linearly frequency …

Operation of a laser interferometer with a noncooperative target surface, and on a
substantial span of displacement (1 m), is reported for the first time to our knowledge. In the …

Self-mixing laser sensors show promise for a wide range of sensing applications, including
displacement, velocimetry, and fluid flow measurements. Several techniques have been …
