Structured Fog Obscuration Properties

Abstract

This work investigates the optical penetration of thermally produced infrared radiation through structured fog patterns and the assessment of the efficacy of various fog patterns that may lead to a technique to create artificial shrouds that are effective while also being minimally perceptible. Dynamic fog structures were created in front of geometrically shaped targets of various temperatures. The fog dynamics was controlled using timed spray nozzles in several different configurations with respect to the targets. Real time videos of the obscured scene were recorded in three bands: visible(VIS), mid-wavelength infra-red(MWIR) and long-wavelength infra-red(LWIR). Several approaches of machine learning are suggested to analyze the results and evaluate the ability to produce the desired effect from the structured fog.
