Abstract
The chromatic intensity and thermal mechanism are vital segment for protection of military target in ultraviolet (UV)-visible (Vis)-infrared (IR) imaging. Defense operations need to confront with UV-Vis-IR imaging to distinguish/conceal the target from combat background (CB). The key purpose of this experimentation is to develop the imaging and optical intensity concepts of chromatic appearance for concealment, detection, recognition, and identification (CDRI) of Cr oxide coated target signature against hyperspectral and digital camera imaging in UV-Vis-IR optical signal. Chromatic intensity of Cr oxide formulated polyamide 6,6 (PA-6,6) fabric was examined by Vis-IR-hyperspectral imaging (HSI) in 400 nm, 500 nm, 600 nm, 700 nm, 1000 nm, 1300 nm, 1600 nm, 1900 nm, 2200 nm, 2500 nm. UV-Vis-IR-HSI has been experimented by international commission on illumination (CIE); red-green-blue standardized color scale for concealment and detection in UV-Vis-IR optical ranges. Concealment of target signature was observed in 400 nm, 500 nm, 600 nm, 700 nm, 2200 nm and 2500 nm when Cr oxide coated PA-6,6 fabric was scanned in 22,948 μs (microsecond)-Vis-HSI and 10,500 μs-IR-HSI. The optical reflection and CIE-chromaticity of Australian grass, Bothriochloa Pertusa, woodland CB and Cr oxide coated PA-6,6 fabric have been observed similarity under UV-Vis-IR optical assessment.
