On the Development and Characterization of a Transparent Enclosure for 360° View Video Cameras to Observe Fire Dynamics in Situ



Matthew S. Hoehler


360-degree video recorded in fires provides a unique perspective that allows the viewer to change the field of view as regions of interest vary in space and time. Use of 360-degree and traditional cameras at some locations in intense fires for extended durations has been hampered in the past by the high levels of radiant heat flux that will damage the camera imaging sensor. This paper describes how a thin (≈ 30 mm) layer of moving water, i.e., a heat exchanger, can be used to significantly reduce unwanted infrared radiation from a fire while allowing visual imaging using a simple and inexpensive enclosure. Essential details to replicate this system are provided and three illustrative example deployments are discussed.
