ABSTRACT:
Acousto-optic multi-channel space integrating correlators and methods of using the same are disclosed. The correlators consist of a single channel acousto-optic cell illuminated by a light source, with the light from the cell imaged onto a second acousto-optic cell, typically a multi-channel cell, with the light between the two cells being single sideband filtered so as to pass only the desired components. The light from each channel of the second acousto-optic cell is directed to a respective light detector, or utilizing a segmented lens system, is split so that different portions of the light from each channel are directed to a different respective light detector. The acousto-optic cells and the light source are oriented so that the light is incident upon the first acousto-optic cell at the Bragg angle, the DC and a first order component of light from the first acousto-optic cell is incident upon the second acousto-optic cell at the Bragg angle, and the DC component and the first order diffraction component as again diffracted by the second acousto-optic cell is directed to the respective light detector. The result provides for a direct complex correlation between an input signal for the first acousto-optic cell and each of the references applied to each channel of the second acousto-optic cell, useful in synchronization, demodulation and other applications. Various applications of the acousto-optic multi-channel space integrating correlators and methods of preprocessing frequency hopped signals to reduce processor bandwidth requirements are disclosed.
