Abstract

Airborne scattering media, such as fog, obstructs imaging by destroying the one-to-one object to image mapping relationship through a multiple scattering process. Existing research in this area is predicated on developing methods to image despite this scattering media, and relatively little attention has been paid to the reverse imaging goal—of using scattering media to intentionally obstruct imaging in a controlled manner. In this work we are investigating how a plume of engineered aerosol can create an asymmetric vision environment— in which ease of imaging tasks are dependent on view direction. Surprisingly, the principle of electromagnetic reciprocity does not appear to preclude such an outcome. Our approach uses engineered asymmetrically scattering aerosol particles under real-time acoustic alignment. In this talk, I will share our initial work to develop an understanding of the optical effects of asymmetric single-particle scattering and how multiple scatterings from an aligned array of such particles translates into degradation of real-world imaging capabilities.
