Design of Camouflage Material for Visible and Near Infrared Based on Thin Film Technology

摘要

Visible light and near infrared based camouflage materials achieve good stealth under traditional optical detection equipment, but its spectral differences with green plants can be taken advantage of by high spectrum based detection technologies. Based on the thin structure of bandpass filter, we designed an optical film with both green and near infrared spectrum. We conducted simulations using transfer matrix methods and optimized the result by simplex methods. The spectral reflectance curve of the proposed thin film matches that of green plants, and experiments show that the proposed thin film achieve good invisibility under visible light and near infrared in a wide viewing angle.
