Abstract
A method for performing light-based calibration of optics with caustic surfaces. The method includes mapping a light detecting device to a programmable light source. Then, the method includes operating a calibration light source to direct light onto one or more caustic surfaces of an optical assembly, e.g., an assembly of one or more lenses, facets, lenticules, and lenslets. The method may then involve, with the light detecting device, capturing an image of a projection surface of the optical assembly, which is opposite the one or more caustic surfaces in the optical assembly, as the projection surface is illuminated by the light from the light source. Further, the method includes processing the captured image, along with the mapping of the light detecting device to the programmable light source, to generate a calibration map of the optical assembly including the caustic surfaces.
