Compact Self-Mixing Vibrometer for Application to Burglary Detection

Silvano Donati and Sheng-Kwang Hwang

Not Accessible

Your library or personal account may give you access

Abstract

A laser-diode self-mixing vibrometer with a new, minimum part-count analogue processing of fringe signal is developed. It detects ambient vibrations with high sensitivity and is demonstrated to be an excellent burglary intrusion detector, on a range up to several meters.
