Design and analysis of asymmetric vision from a plume of oriented synthetic aerosol particles

The introduction of scattering media along an imaging path typically results in a deterioration of image quality, as scattering re-directs light into off-axis trajectories. Our goal is to create an asymmetric vision environment by exacerbating this deterioration of image quality along only one view direction, while the opposing view direction retains reasonable vision quality. This environment will be imposed by a plume of engineered aerosol particles, causing asymmetric image information propagation between forward and backward view directions. This aerosol particle is necessarily asymmetric in both geometry and absorption behavior, resulting in scattering mean free path length differences between forward and backward propagation directions. Here, we present our current particle design, the microclub, and initial optical modeling results that indicate the microclub particle could affect such an asymmetric vision environment.
