The authors describe the implementation of a tracking algorithm using one eyelet (simulated by a quarter-pitch gradient-index lens) for a multiaperture vision system (MAVS). The compound-eye of an inset served as the inspiration for the MAVS concept. The technique for location determination is based on the quality and polish of the ends of the fiber-optic cables used. The tracking algorithm utilizes the digitized intensity output to plot the intensity function vs. location of the object. Edge detection of this function provides a useful means of estimating the location of the object at a specific time. Further evaluation of this function provides insight to other tracking algorithms.
