Abstract: A method and apparatus for measurement of the brightness, flow velocity and temperature of radiant media. A substantially collimated beam (3) of light is directed to a linear polarizer (5) through an interference filter (4). An electro-optically active birefringent crystal (7) separates the linearly polarized output of the polarizer (5) into two characteristic waves and introduces a final phase delay between the wave. The birefringent crystal (7) is electro-optically modulated to introduce a variable phase delay between the characteristic waves. The resultant characteristic waves are combined to interfere and the combination is sampled to produce a signal from which the emission moment of the radiant media can be determined.
