Imaging Sphere IS-SA™ for BRDF and BRDT Determination
The IS-SA™ scatter and appearance measurement system from Radiant Vision Systems integrates a focused light source, directly illuminating a material sample to measure scattered light. The IS SA can accurately and rapidly characterize surface roughness, imperfections and diffusion properties for a wide range of reflective surfaces and transmissive films. The IS-SA generates detailed BRDFs and BTDFs with finer angular resolution and greater speed than goniometric systems. It is designed for use in both R&D and production quality control applications for material characterization and quality assessment, and for generating libraries of BSDF measurements for computer modeling and rendering. No dark room is required for BRDF measurements.
