- Abstract:
- This study investigates how the geometry of illumination affects the visibility of a target as seen by a camera in a foggy environment. The visibility is expressed in MOR (Meteorological Optical Range). An experimental setup was developed using a transparent Fog Chamber (FC) that allows fog generation, enabling visibility variation along the optical path without the need for large-scale fog environments. A moving light source provides the lighting. We compare the MOR calculated with the camera-captured image contrast with a reference MOR estimated with an illumination-independent system. The results show the MOR perceived by the camera varies with the lighting angle for angles higher than 15°.
