NOVEL METHOD FOR COMPOSITIONAL ANALYSIS OF HEPARIN

Not Available The Aberdeen Test Center (ATC) conducts underwater tests of warheads and projectiles including shaped charge, blast, and projectile impacts. Physical Sciences Inc. (PSI) has a diverse experience base in the design(including for ATC), fabrication and fielding a number of repetitively pulsed laser illumination systems coupled to high speed imaging systems. Our proposal addresses using high-speed digital cameras coupled with multiple short pulse laser illumination and bandpass filters for this specific underwater application. COTS or semi-custom laser systems have been used. The system will have the advantages of submicrosecond laser pulses stopping the action of high speed explosively driven events, e.g., a shaped charge jet, as well as overwhelming the self luminosity associated with the event by the combination of the illumination source having high spectral brightness and a moderately narrowband passband filter on the imaging system. This proposal addresses the tradeoffs of operating in water with limited clarity as well as the survivability of illumination equipment and image recording system. The use of expendable fiber optic system for transmitting laser pulses and a periscope device for the imaging system will physically remove the key equipment to a safe distance where structural hardening is practical. BENEFITS: Once the requirements are established for illumination and underwater housings; design studies, point design and proof of concept experiments will be
