Abstract
We describe the implementation of a scale-invariant binary phase-only matched filter using a 128 x 128 ferroelectric spatial light modulator . A 5-dB discrimination was obtained between a 10-image training set o f highly correlated characters (E's and F's) over a scale range of 1.0 to 1.5.
