Abstract
Disclosed herein is a novel system and method for the remote characterization of visible emissions, and more particularly, to compact, optical sensors which can remotely measure the opacity of a visible emission plume from a stationary source. Assessing visible emissions is important for compliance with environmental regulations and to support the regulatory reporting needs of Federal and State inspectors. By reducing the power consumption of the laser source and the signal processing, a compact, handheld or hand portable, battery-operable opacity measurement system can be realized while allowing eye-safe operation. The system and method may also be applied to non-stationary sources.
