Physical and chemical degradation behavior of sputtered aluminum doped zinc oxide layers for Cu(In,Ga)Se2 solar cells

Sputtered aluminum doped zinc oxide (ZnO:Al) layers on borosilicate glass were exposed to damp heat (85 C/85% relative humidity) for 2876 h to accelerate the physical and chemical degradation behavior. The ZnO:Al samples were characterized by electrical, compositional and optical measurements before and after degradation. Hall measurements show...

Fast and true-to-life application of daytime colours to night-time imagery

We developed a fast and efficient method to derive and apply a natural colour mapping for night-time imagery from multi-band sensors. The colour mapping is derived from the combination of a multi-band image and a corresponding natural colour reference image. The mapping optimizes the match between the multi-band image and the reference image,...

Dichoptic fusion of thermal and intensified imagery

Subjects used the dichoptic combination of a monocular image intensifier (NVG) and a monocular uncooled microbolometer (LWIR) to detect and localise both visual targets and camouflaged thermal targets while moving through a dimly lit complex environment. The NVG imagery enabled the subjects to move freely through the environment with high...
