Study and Development of Infusible and Incorrodible Identification Tags and Microdots.

摘要

The program covers the development of a new type of personnel identification tag, conceived by the Army Natick Laboratories, for identifying personnel who have been subjected to cataclysmic events. In particular the tags are to be incorrodible and infusible at 2000F. The tag is 1 in x 2 in and contains a facial image, fingerprints, and alphanumeric characters. Both chemical and laser etching techniques have been investigated. For use with the ID tag, a cable type nicklace, which will withstand the temperature required but will fail in tension in order to protect the wearer, has been designed. Also, an investigation has been made of microdots, which include the basic features of the tag. Single pulse laser recording, for selective evaporation of a surface deposited on a substrate, is the mechanism investigated.
