Design of coupled mace filters for optical pattern recognition using practical spatial light modulators [PDF]

open access: yes
Spatial light modulators (SLMs) are being used in correlation-based optical pattern recognition systems to implement the Fourier domain filters. Currently available SLMs have certain limitations with respect to the realizability of these filters ...
