Research abstract
A NARROW-BAND SPECTRAL FILTER IS A CRITICAL ELEMENT IN HIGH-RESOLUTION LIDARS FOR ATOMSPERIC STUDIES. ACCOUTO-OPTIC TUNABLE FILTERS (AOTF) OFFER THE ADVANTAGES OF LARGE OPTICAL THROUGHPUT, RAPID TUNING OVER WIDE SPECTRALRANGE, AND INHERENT MODULATION CAPABILITY, AND ARE THEREFOREWELL SUITED TO THE LIDAR APPLICATIONS. THE BASIC DEFICIENCYOF PRESENT AOTF TECHNOLOGY IS THE LIMITED SPECTRAL RESOLUTION ACHIEVABLE, INNOVATIVE APPROACHES FOR RESOLUTION ENHANCEMENT WILL BE EXAMINED IN THE PHASE I EFFORT OF THIS PROJECT, WHICH INCLUDES A THEORETICAL INVESTIGATION OF THE NEW APPROACHES AND FEASIBILITY DEMONSTRATION EXPERIMENTS FOR THE SELECTED OPTIMUM APPROACH.
