We compare the experimental performance of 12 variations of the binary joint transform correlator (BJTC) when used for fingerprint identification. Three hardware architectures were used: a single spatial light modulator (SLM) BJTC, a BJTC using two input SLMs, and a chirpencoded BJTC using two input SLMs. These correlators were implemented on the same hardware setup with minor modifications. With each hardware configuration, four binarization techniques were implemented: global threshold, Fourier plane windowing, frame subtraction, and frame subtraction followed by windowing. A set of 10 experiments was used to characterize the output peak intensity, peak-to-noise ratio, and discrimination ratio. The same set of experiments was run on each of the 12 correlator variants.
