Abstract

In this work, we implemented a three-dimensional (3-D) laser range imagingsystem using the well-known self-mixing effect in a frequency-modulated semiconductor laser diode. The system generates 3-D point sets of a scene, using a single semiconductor laser diode serving both as the light source andas the detector. The experimental imaging accuracy was measured to be 0.87mm at a distance of 0.55 m after some filtering. This paper focuses on thetheoretical description of the self-mixing effect by presenting a survey of the existing literature as it applies to our specific implementation, followed by some experimental results.
