Free-Space Optical Link to an Explosive Ordnance Disposal (EOD) Robot
Abstract
The Optical Sciences Division, in collaboration with scientists from the Remote Sensing Division and the Naval Center for Space Technology, field-tested a free-space optical (FSO) link for a counter-IED (improvised explosive device) robot. Traditional radio frequency (RF) link command and control of these robots is not possible in the presence of IED RF jammer systems. To solve this problem, a freespace optical link using quantum well based modulating retroreflectors was prototyped and installed on one version of a robot. Two field tests were run. During the first test at the Naval Explosive Ordnance Disposal Technology (NAVEODTECH) Division, Indian Head, the link operated in the presence of RF jammers and showed continued command and control on the robot without interference. The system was demonstrated to several military personnel including the Program Executive Officer (PEO) for Littoral and Mine Warfare. During the second test, at Naval Surface Warfare Center Dahlgren, the link was tested for range. A maximum range of 1 km, limited by line of sight, was demonstrated. This matches the maximum range for the RF link.
