Abstract
THE OBJECTIVE OF THE PROPOSED WORK IS TO PRODUCE FAST SWITCHING, LOW-POWER, LOW-COST, HIGH RESOLUTION OPTICAL PHASE CONJUGATORS FOR NOVEL APPLICATIONS TO TRACKING NOVELTY FILTERING. THE OPTICAL PHASE CONJUGATING DEVICE DESCRIBED IN THIS PROPOSAL USES A SI:H PHOTOSENSORSIN THE PHOTODIODE MODE TO MODULATE THE INDEX OF REFRACTION OF A HIGHLY BIREFRINGENT (DELTA N = 0.2) FERROELECTRIC LIQUID CRYSTAL (FLC). THESE DEVICES CAN BE USED TO BUILD NOVELTY FILTERS, AN OPTICAL SYSTEM THAT EXPLOITS THE PHASE REVERSAL PROPERTIES OF THE CONJUGATOR. THE NOVELTY FILTER HAS A DYNAMIC SCENE AS ITS INPUT, AND ITS OUTPUT IS ONLY THE INFORMATION THAT SCENE AS ITS INPUT, AND ITS OUTPUT IS ONLY THE INFORMATION THAT SCENE THAT HAS CHANGED IN THE LAST TIME INTERVAL. THE FLC PHASE CONJUGATOR INCREASE THE BANDWIDTH OF THE NOVELTY FILTER TO OVER 10 MHZ FROM THE 120 HZ OBTAINED WITH CONVENTIONAL PHOTOREFRACTIVE PHASE CONJUGATORS.
