Abstract
Systems and methods for generating an image of a gemstone under evaluation which is coded according to angular ranges in its angular spectrum across a broad range of tilts, this allows for scintillation of a gemstone to be demonstrated based on a singular coded image of the gemstone. Scintillation information is thus presented in a single image, or as a plurality of images showing fire scintillation, flash scintillation, and other scintillation related criteria as a series of static images.
