From: Whole-infrared-band camouflage with dual-band radiative heat dissipation
The sample is placed on the heat stage, along with the Cr reference and blackbody reference (BB), and was heated up to 200 °C. a, b The radiative temperature variation of the sample/Cr/BB and the thermal images within the MWIR and LWIR bands. c The radiative signal intensity variation of the sample/Cr/BB under different heating temperatures within the SWIR band, and the thermal image at 200 °C. The experimental radiative temperatures (represented by circles in the left figures) were calculated by averaging the values in the rectangle areas in the thermal images obtained at various heating temperatures. The dashed lines represent the numerical calculations of radiative temperatures for various band average emissivity (0.1, 0.2, 0.4, and 1)
