In this paper, we study the thermo-optical impact of a window on the imaging performance of electro-optical (EO) and infrared (IR) multi-sensors. For demonstration, high-temperature imaging experiment was performed with a broadband EO/IR window heate

In the paper, we report the experimental demonstration of thermo-optic impact on imaging performance. To create the temperature-controlled environment, we built the optic heater which can heat the IR window over $700°C. For imaging experiment, we pl

In multispectral and hyperspectral sensing, there is a growing need for a versatile sensor capable of adapting response and improving detection of hard-to-find dynamic targets of interest in contested environments. Such on-the-fly adaptivity in curre

Two model-based algorithms for edge detection in spectral imagery are developed that specifically target capturing intrinsic features such as isoluminant edges that are characterized by a jump in color but not in intensity. Given prior knowledge of t

In previous work, the present authors discovered the resonant splitting phenomenon of a plasmonic perforated gold film (PGF), as the incident light comes in the polar angle. However, in reality, the light through the imaging lens could be incident on

In the authors' previous work, the effect of a plasmonic metal hole array (MHA) as integrated on the infrared (IR) photodetector was demonstrated and its performance particularly at a normal incidence was analysed. However, in IR imaging, the associa
