Inertial fusion experiments require real-time, highly-accurate tracking of targets during each injection cycle.  Conditions within the chamber influence the target’s flight, preventing accurate position predictions; however, the effective ignition reaction, using laser or ion beams, requires a targeting precision of 0.02 mm.  This project will develop a new and reliable target-tracking system that is capable of real-time tracking of the position of a high-speed (400 m/sec) target.  The tracking system will dynamically interact with the beam steering system to ensure effective and reliable ignition at every injection cycle.  In Phase I, a new Interferometric Target Tracking System was designed, developed, and tested to demonstrate the feasibility of the concept.  Optics hardware and software were also developed and tested.  In Phase II, the proposed interferometric tracking system design will be optimized, and an engineering prototype will be assembled and integrated into the existing target injection system.  Comprehensive testing of the overall system will be performed under realistic conditions. 

Commercial Applications and Other Benefits as described by the awardee:  When fully developed, this technology should be the core element in future interferometric tracking systems for inertial fusion power stations.  Commercial applications include new test and measurement devices, machine vision for manufacturing, studies of high speed movements, and military and security applications.  Separate parts of the system should have use in industrial applications, projection profilometry, and optical shop testing.
