A robust, self-aligned, polarization independent, pure phase filter was obtained using the intensity dependent refractive index (IDRI) medium, zinc tetraphenyl porphyrin (ZnTPP), a metalloporphyrin. An optical image processor with ZnTPP as the phase filter was designed so that both weak and strong p
