To address the need for improved techniques to determine the structural stability buildings and other structures, Physical Optics Corporation (POC) proposes to develop a new Real-time Holographic Structural Instability Evaluation (RHOSIE) system based on novel temporally modulated holography (TMH), with acoustic excitation and highly sensitive rewritable photothermoplastic recording film. The RHOSIE system holographically records and reconstructs the surface vibration pattern as an indicator of material structure stability, characteristic of a material structure that is acoustically stimulated by a transducer. The overall vibration pattern recorded in the holograms can be read out by a CCD camera, and the data processed to extract the high-frequency components resulting from the stress distribution in the material structure of the building. The mapped stresses on the structure can be analyzed to quantify the structural integrity to warn of serious instability or pending collapse. In Phase I POC will design, analyze, and assemble a breadboard prototype to demonstrate the feasibility of RHOSIE. In Phase II we will focus on an optimized, miniaturized, and fully functional packaged portable prototype system for testing and evaluation at a HSARPA selected facility.
