Abstract
A photodiode array spectrometer for determining the spectral composition of a polychromatic beam of radiation comprises an array of photosensitive elements intercepting different wavelengths of the polychromatic beam of radiation. An output signal representative of the charge accumulated by a charge amplifier circuit is obtained each time a predetermined number greater than 1 of photosensitive elements is scanned such that the output signal is representative of the integral of a plurality of the amounts of radiation intercepted by a corresponding plurality of the photosensitive elements.
