Abstract : The features of the detection process of a TIC have been studied with a computer simulation and optimal conditions of operation allowing a reliable detection of the correlation peaks over the whole operating window have been established. These optimal conditions of operation have the further advantage to be associated with a graceful degradation of the performances of the detection process if the parameters drift away from their optimal value. Of particular importance is the fact that the detection process is not sensitive to large change of temperature when an optimal fringe system is used. It was also demonstrated that the exact shape of the sensitivity response of the element of the detector array is a parameter of secondary importance in the evaluation of the performance of he detection process. Experimental verifications of the optimal detection process has confirmed their capability to detect reliably correlation peaks over the whole field of view of the TIC.
