Time-Integrating Correlators TICs use either surface integrated- optics or bulk acousto-optic interactions. This technical note documents the development of a signal processor that includes a TIC designed to operate with a large parallel gain and a digital post-processor DPP. The DPP controls both the input of signals to the TIC and the collection and analysis of optical data from the TIC. This note also reviews the principle of operation of TICs, discusses the selection criteria and compromises involved in selecting the various components and describes the DPP, and presents the algorithms available to analyze the output of the TIC.
