Research abstract
The NASA Constellation program has a need to non-destructively test (NDT) non-metallic materials (foams, Shuttle Tile, Avcoat, etc) for defects such as delaminations and voids. While imaging systems at terahertz frequencies (0.3 to 3 THz) have been demonstrated for 2D imaging of similar materials, they have not yet demonstrate full 3D volumetric imaging. To meet this need, LongWave Photonics proposes to use high-power, low-frequency terahertz quantum cascade lasers (QCLs) developed at MIT, to demonstrate 3D imaging using Laser Triangulation. By using high-power QCL sources, large signal to noise ratios (SNRs) are attainable, resulting in resolution of subtle defects at fast scan speeds. The shorter wavelengths emitted by QCLs, 60 to 250
