One snap-shot multi-angle spectrum measurement system

The present invention discloses an one snap-shot multi-angle spectrum measurement system. It comprises an optical transform module, an angle selection module, a color split module, a first light collector, a second light collector and a 2 dimensional detector, wherein the optical transform module performs a transformation to the outgoing light from a light source and transforms the light into a light signal in spatial distribution, and the other modules help obtain the spectrum in every angles of the light source. With the implementation of the present invention, light spectrum detection makes great progress in both obtained with only one single-detection and detected without having to perform scanning, which not only reduces the detection time required, but also eliminates detection errors due to optical or mechanical deviations or discontinuities.
