Abstract
Abstract A SYSTEM USING A MAGNETOSTRICTIVE DELAY LINE FOR CONVERTING THE INTERVAL BETWEEN PULSES CORRESPONDING TO THE FIRING OF A LASER BEAM AT A TARGET AND CORRESPONDING REBOUND PULSES INTO A TARGET RANGE INDICATION. THE INTERVAL BETWEEN THE LASER FIRING AND REBOUND PULSES IS COMPARED TO THE DELAY LINE INTERVAL AND A MOTOR IS DRIVEN IN RESPONSE TO THE DIFFERENCE BETWEEN THE INTERVALS FOR AUTOMATICALLY TRACKING THE TARGET. A POSITION SENSOR CONNECTED TO THE MOTOR SHAFT SENSES TARGET RANGE INFORMATION FOR PROVIDING A CONTINUOUS TARGET RANGE DISPLAY.
