PHOTONICS APPLIED: HOMELAND SECURITY - Threat identification demands new imaging technologies

摘要

Recognizing that the potential for national-security breaches along our borders and in our waterways is significant, imaging companies and research organizations are stretching existing technologies to better identify the people and things that could constitute a significant threat. To combat the ever-present threat to homeland security, photonic companies and research institutions are constantly developing new imaging technologies aimed not just at target identification, but also at maintaining constant and enduring contact with the target after identification (see "Persistent surveillance," p. 60).
