Abstract
An analysis is carried out of the variation of photoelastic fiber optic sensor response with optical source spectral linewidth. An analytical expression is derived to predict this variation and incorporated into a computer model based on the properties of a known broadband optical source and silicon photodetector. The model is then compared with experimental results and the possible advantages of the use of broadband optical sources are discussed.Keywords
