Abstract

In this research there has been a description and studying for Fiber Arrival Time (FAT) technique. The research has depended on a theoretical analysis way for the FAT technique that is mainly used as a sensor and detector for the detonation waves (thermal waves) that is produced by high explosives. Several explanations for the output optical signal in FAT diagnostic have been introduced, the suggested by previous researches as well as the suggested by this research. Wien's displacement law has been depended to measure the wavelength of the output optical signal. Also, heat measurements have been performed in this research and each of heat transfer coefficient and heat gradient in FAT diagnostic has been measured. There has been a comparison by using several other elements like copper, silver and gold as probable substitutes for aluminum that has been used in FAT.
