Abstract
This paper will examine how Avalanche Photodiodes (APD) and Infrared Pulsed lasers (PL) are used and optimized to provide the "intelligence" to smart weapons. The basics of APD's and PL will be covered and the principle "time of flight ranging" which is the underlining principle of 3D laser radar will be illustrated. The time of flight principle is used for range finding, lidar, 3D laser radar and speed measurements - this information can then be used to provide intelligence to the smart weapon. Examples of such systems are discussed and illustrated, for example: Cluster bombs, Proximity fuses, and how laser range finding systems can be incorporated with GPS to produce effective and lethal weapons. The APD's that are discussed include silicon APD's for cost effective weapons, and 1550nm APDs for eye-safe systems. An overview of the different PL's will be outlined, but the focus will be on 905nm laser pulsars for cost effective laser weapons.
