A multi-channel acousto-optic spectrometer employs a multi-channel Bragg cell, Fourier transform imaging optics and two-dimensional charge coupled device photodetector array to simultaneously process a plurality of parallel channels of respectively adjacent frequency bands of a wideband radio frequency signal. The signal modulation and optical transmission characteristics of the spectrometer are such that the respective acousto-optic channels to which the respective sub-bands portions of the signal are applied do not interfere with one another and are imaged upon closely spaced regions of the two-dimensional photodetector array. The opto-electronic responses of the respective imaging regions of the array are transferred from an imaging area of the photodetector array, upon which a multi-channel acousto-optically modulated light beam is projected by the spectrometer's Fourier transform-imaging optics, to a non-imaging area of the photodetector array, so as to permit a new spectrometer input signal to be imaged onto the two-dimensional photodetector array. The contents of each frequency channel of a respective sub-band are then transferred in parallel to an output accumulator register, which is read out serially and digitized for application to downstream signal processing and display circuitry.

An infrared lens is made from a moldable IR transmissive material and has an optically significant surface with a surface relief holographic grating. The moldable IR transmissive material is an arsenic selenide glass. The lens and the optically significant surface are manufactured as a unitary structure in a molding operation.
