This accessory converts the TPS spectra 3000 in to a flat-bed imaging system. Samples as large as 100mm x 100mm can be placed in the unit and raster scanned using a software controlled motorized scanning table. Areas up to 80mm x 80mm can be scanned with a user-selected distance between measurement points and up to 3 mm penetration depth. Using the TeraView supplied Image and Data analysis software, thickness maps and cross sectional images can be generated from the data collected and physical features such as buried cracks, defects and air pockets can be non-destructively detected.
