This report summarizes the results of a program to develop optical radiation sensors for fire detection using polymeric pyroelectric sensing elements. Emphasis has been placed on techniques for constructing such devices, including methods of enhancing the pyroelectric response. Materials investigated included polyvinyl fluoride PVF and polyvinylidene fluoride PVF2. Six sensors were developed and delivered to the sponsor. Highlights reported include achievement of a value of specific detectivity, D 2 x 10 to the 8th power cm. square root of Hz.1w and the construction of a set of sensors useful over a wavelength range extending from the ultraviolet to the infrared. Methods of characterizing the performance of sensor elements are described. Author
