Abstract
A spectrometer apparatus uses a spectrum resolving sensor containing an opto-electronic monolithic array of photosensitive elements, each preferably sub-millimeter in size and pitch, and a continuous variable optical filter, that is permanently aligned with the array. Polychromatic light passing through the variable filter is spectrally resolved in accordance with the local filter transmission function, and is incident upon the photosensitive elements in the array. The electrical output of each element in the array is thence a function of the local transmission function of the variable filter and the output of all the elements provides the spectral contents of the polychromatic light. High spectral resolving power is obtained by subtraction of the output signal of adjacent elements in the array.
