Abstract: A system for water cut sensing in an oil-water flow includes a laser-based spectroscopy sensor and a computer system. The laser-based spectroscopy sensor includes a first set of lasers that expose the oil-water flow to a first incident signal, a first photodetector that collects a first transmitted signal, the first transmitted signal being a component of the first incident signal transmitted through the oil-water flow, a second set of lasers that expose the oil-water flow to a second incident signal, and a second photodetector that collects a second transmitted signal, the second transmitted signal being a component of the second incident signal transmitted through the oil-water flow. The computer system that calculates the water cut of the oil-water flow based on the first transmitted signal and the second transmitted signal.

Abstract: A laser-based detection and analysis system for detecting plural members of volatile organic compounds includes a measuring unit configured to simultaneously measure a spectrum of the plural members of the volatile organic compounds located in a measuring chamber, with a laser beam having a wavelength of about 3.3 ?m, and a data processing unit including a deep neural network, DNN, configured to process the spectrum measured by the measuring unit and to output an individual concentration of each of the plural members of the volatile organic compounds. The DNN is configured to update a weight Wk for each member of the plural members by using hidden layers having plural nodes, each node having an activation function and an optimizer.
