Abstract

Acoustooptic Bragg cells are used in a variety of real-time signal processors such as RF spectrum analyzers convolvers and correlators. The ultimate achievable bandwidth of acoustoooptic Bragg cells is limited by the acoustic attenuation of the interaction medium.¹ For certain applications such as the coarse channelizer at the rf front end, a more suitable approach is to implement the spatial light modulation using the electrooptic effect.
