Abstract : The Active Optical Miss-Distance Indicator (AOMDI) can be described as an arrangement of three optical fuzes of different ranges. It uses the principle of geometrical cutoff in three optical receivers with overlapping range intervals to produce five intervals of distance ('bins'). The greater angular coverage required by the AOMDI is obtained by combining nine basic quadrants in a configuration that results in a good approximation of 4 pi steradian coverage. In the report the results of a study of the performance of an AOMDI are presented. For this study assumed values of all parameters influencing performance correspond to the best presently available. Concurrent with the study a demonstration model of one quadrant of the AOMDI was built. The purpose of this task was to verify some of the findings of the study.
