Abstract
A flow control system for controlling exhaust flow can measure effluent escaping from the exhaust hood at a given flow rate. An interferometric detector can measure fluctuations in fluid properties external to and/or in the vicinity of the exhaust hood. The flow control system may vary a flow rate of the exhaust hood and/or control exhaust hood structures responsive to the measurements to contain the effluent while minimizing the exhaust of air from the occupied space.
