Abstract : The report contains the analysis and design of a unique optical-angle measuring device. This device was constructed to measure the error angle off boresight of a particular radar. Development of the device was divided into three major phases: optical design, photodiode considerations, and electronic processing. Laboratory tests of the device showed that it met and exceeded the angle accuracy requirement of plus or minus one milliradian. Additional uses for the system could include any application requiring angle alignment where it is feasible to mount a flashing light on the target to be measured. (Author)
