Compact Profilometer and 3-D Display

Digital measurement and visualization of topography of large structures from a distance is necessary for terrain simulation, battle damage assessment, and a number of commercial applications including manufacturing; specifically, visualization in 3-fl with scanning capability is immediately required. To address Army current need and commercial opportunities, Physical Optics Corporation (POC) proposes to develop an Autostereoscopic 3-fl Profilometer (ASDP) system. The proposed A3DP system development effort advances the existing technology by innovatively integrating three technologies: (I) Absolute interferometer (ii) High-speed scanning profilometer based on absolute interferometer and high-speed variable microprism scanning assembly (iii) Real-Time Autostereoscopic 3-D visualization device that doesn't require eyewear. In Phase I we will complete the design and evaluation three technologies so that the A3DP feasibility demonstration can be accomplished. In Phase II a compact, portable and cost effective ASDP system will be fabricated as a preproduction model. The proposed A3DP system will be immediately useful for Army battle damage assessment and simulation. A3DP obtains critical 3-fl information to be transmitted and evaluated remotely. Commercial applications include biometric identification, interior design, stereolithography, and landscaping.
