Abstract
A high speed high resolution spectral sensor is formed by placing a cascade of chained wide field-of-view Mach-Zender interferometers inside a dispersive sensor between the sensor's grating and the focusing lens. Also is disclosed an optical filter with wide field-of-view capabilities. Such a filter is formed by inserting a plurality of gap plates of certain thicknesses and refractive indices. The invention provides formulas for calculation of optimal dimensions for such gap plates.
