Abstract

A low-cost high-speed demodulation system based on a fiber grating spectral filter has been developed to support strain and temperature sensing in composite panels. This system has also been used to support high-speed impacts on composite panels. This paper will describe the system, its current state of development, and some of the applications it is supporting.
