Abstract:
Holographic Depth Contouring
This innovation integrates the well-developed theories of two-color holography and
light striping with three new technological opportunities. These new technologies
include easily-tunable pulsed lasers, high-frame-rate digitizing electronic cameras,
and high-performance digital signal processors. Phase I will investigate the feasibility
of integrating the above theories and technologies into a three-dimensional imaging
system for non-intrusive measurement of deformation, vibration, stress, and nozzle
thrust vector. This project applies to health monitoring sensors for solid-rocket-motor
1/components and interfaces. Critical proof-of-principle experiments will be carried
out in an electronic holography laboratory and the resulting holographic image analyzed
on a vision system using light-stripe analysis software. Phase I will produce a rudimentary
design, performance model, and technical risk analysis.
The holographic depth-contouring technology has two main areas of commercial potential:
imaged three-dimensional metrology and imaged vibration analysis. End uses would
be by firms manufacturing automobiles, aircraft, aerospace components, and audio
speakers and other firms in which metrological and vibration imagery is important.
