METHODS FOR WAVELENGTH DETERMINATION OF MONOCHROMATIC LIGHT BEAMS

Methods for wavelength determination of a monochromatic beam are described. The methods involve a detector unit containing at least one variable filter and at least one pair of photo detectors. The detectors have photo sensitive regions with their areas varying with the position in one direction. Th...
