Abstract
An in-line fibre etalon sensor system using the laser chirp and three wavelength arc-tangent algorithm to measure the absolute phase is studied. We proposed and proved the new algorithm by performing the experiments. As a result of signal processing, the minimum detectable strain was 6.3 /spl mu/ strain.
