Transform-ratio ternary phase-amplitude filter formulation for improved correlation discrimination
TL;DR: Performance of ternary-valued (-1,0,1) correlation filters based on the ratio of spectral energies of target and nontarget patterns is investigated, and results confirm the intuitive expectation that such filters can enhance signalto- clutter and discrimination performance for target recognition in the presence of large amounts of input noise.
Journal ArticleDOI
Design elements of binary joint transform correlation and selected optimization techniques
TL;DR: A new power spectrum binarization technique is introduced that eases experimental implementation while significantly improving binary joint transform correlation performance, including practical dynamic range limitations and achievable threshold levels.
Journal ArticleDOI
Real-time coherent correlator using binary magnetooptic spatial light modulators at input and Fourier planes
TL;DR: An experimental correlator using the Light-Mod magnetooptic spatial light modulator (SLM) devices for real-time modulation of both input images and Fourier plane filters has been constructed and demonstrated and is in good agreement with computer simulations based on the FFT.
Journal ArticleDOI
Implementation of ternary phase amplitude filters using a magnetooptic spatial light modulator.
TL;DR: Ternary modulation can be achieved with a single SLM and improved with improvedrelationd iscrimination and an bee experimentally realized.
Journal ArticleDOI
Design elements of binary phase-only correlation filters
TL;DR: A general formalism for the threshold-line angle variation is presented and related to the special cases of cosine-, sine-, and Hartley-BPOFs and to the general characteristics of the BPOF impulse response.
