Abstract
Disclosed is an open-path optical sensor. Typically, the optical sensor directs UV radiation from a source assembly to a detector assembly along a monitoring path. The source assembly emits UV radiation corresponding to a signal channel and to a reference channel. The detector assembly detects UV radiation corresponding to the signal channel and to the reference channel. The detector assembly is in communication with a data acquisition system, which compares the intensity of the detected UV radiation corresponding to the signal channel to the intensity of the UV radiation corresponding to the reference channel.
