Screen image synthesis system for BSDF measurement and snap shot image

The Screen Image Synthesis meter was proposed to make high-speed BSDF measurement and whole field measurement, but it lacks the spectrum information. We proposed a snapshot hyperspectral technology and applied it to the SIS meter to build up a SIS hyperspectrum meter. It released the full power of SIS system. Besides, the proposed method doesn’t need to add any other bulky optical element. The experiments demonstrated the measurement is trustable in both spectrum distribution and color coefficient temperature distribution.
