Development and Characterization of a Tabletop Fog Chamber at Sandia National Laboratories

Atmospheric fog is a common degraded visual environment (DVE) that reduces sensing and imaging range and resolution in complex ways not fully encapsulated by traditional metrics. As such, better physical models are required to describe imaging systems in a fog environment. We have developed a tabletop fog chamber capable of creating repeatable fog-like environments for controlled experimentation of optical systems within this common DVE. We present measurement of transmission coefficients and droplet size distribution in a multiple scattering regime using this chamber.
