Hyperspectral screen-image-synthesis meter with scattering-noise suppression

open access: yesScientific Reports, 2023
The screen image synthesis (SIS) meter was originally proposed as a high-speed measurement tool, which fused the measured data from multiple sample-rotational angles to produce a whole-field measurement result. However, it suffered from stray light noise
