The diffraction limited resolution of photodichroic materials when used for holographic recording make them desirable candidates as spatial light modulators (SLM) in the frequency plane of the Joint Fourier Transform (JFT) correlator. Since the photodichroics generally have photosensitivities which are highly wavelength dependent, KF:LiF is a particularly good choice because its write and read sensitivities coincide with the strong 514nm and 488nm lines of the argon laser. Experimental results are reported on the use of KF:LiF as a SLM in a JFT correlator. Sections of a linear maximal length pseudo-random sequence with time-bandwidth products of up to 2.56 x 106 are successfully cross correlated.
