ANISOTROPIC LIQUIDS FOR TUNNEL DETECTION, VOLUME 1

Abstract

This work is a continuation of that reported in a ATL-TR-65-62, 'Thermal Detection of Underground Tunnels,' September 1965, and describes an evaluation of the feasibility of utilizing anisotropic liquid films to detect a tunnel one foot below ground and containing a heat source which simulated the thermal effects originating from a hidden human being. Concurrent with this study, a series of plastic films were evaluated for potential use in packaging the AL into a unit suitable for thermal mapping applications. The plastic films generally contributed to a lowering of the AL color appearance temperature with Surlyn A, an ionomer film, exhibiting the least tendency.
