Abstract
In accordance with embodiments of the present invention, a goniospectrophotometer is provided for quickly obtaining a goniospectrum using a goniospectrophotometer. In some embodiments, a parabolic reflector is used to optically transform the angular space of a source at the parabola focus into a linear space and facilitate the use of a single diffracting element and area camera to simultaneously measure the angular spectrum of the source. Spectra corresponding to zenith angles of light reflection by the parabolic reflector can be acquired by a detector and analyzed in a computer.
