title: Operating-curve selection for optical and digital correlation of fingerprints.
abstract: We present a new method for selecting the optimal spatial light modulator operating curve on which to encode an ideal complex-valued filter function. The method is an extension of the optimization procedure that was used to derive the ideal complex-valued filter. To illustrate the method we consider the selection of a typical operating curve of a commercially available LCD and use this operating curve to encode a filter that was optimized for the task of fingerprint verification. We then extend the method to include the selection of the optimal operating curve from a series of synthetic operating curves.
