Design and testing of 3-Level optimal correlation Filters
Previously, we have (lesigueci 3-level filters (suitable for implementation on magneto-optic spatial light modulators) to maxiiiiize the output signal-to-noise ratio (SNR) and to separately maximize Peak-to-Correlation Energy (PCE) that iieasures the correlation peak sharpness. In practice, we want the correlation peaks to he sharp (i.e., large PCE) as well as noise-tolerant (i.e., large SNR). In this paper, we vill present a new method to optimally coiiibine these two desirable properties into a single optimization procedure. Similar methods to trade off SNR versus Peak Efficiency and PCE versus Peak Efficiency will be presented. Both siiiiulation and experinental results will be included.
