This paper presents a theoretical analysis and a comparison with experimental results on
self-mixing interference inside a single-longitudinal-mode diode laser. A theoretical model …

This paper reviews the dynamic effect of thin-slice solid-state lasers subjected to frequency-
shifted optical feedback, which led to the discovery of the self-mixing modulation effect, and …

A compact self-aligning laser radar has been constructed for coherent ranging and
velocimetry using a laser diode modulated by feedback from light scattered from a diffusing …

A laser Doppler velocimeter (LDV) using a semiconductor laser diode (LD) with its self-

A keyboard detects press or release of keys using one or more ranging techniques. Targets
are attached to keys of the keyboard. As keys are pressed or released, attached targets …

A very small and simple velocimeter is presented consisting of a diode laser with a gradient-
index lens in front of it. The basis of the velocity measurement is the mixing that occurs when …

In this work, we implemented a three-dimensional (3-D) laser range imaging system using
the well-known self-mixing effect in a frequency-modulated semiconductor laser diode. The …
