Profile: Omnisens SA produces instrumentation & systems, based on optical metrology and photonics. We produce laser-based photo-acoustic spectroscopy & fiber optic distributed sensing leading to the development of products performance and solutions for emerging market requirements. Our trace gas analyzers combines photoacoustic spectroscopy with a highly sensitive and good detection technique offering monitoring solutions for various industries. Distributed fiber optic sensing technique uses optical fibers to monitor temperature and strain variations at each location along the fiber length. The strain and temperature to which the fiber is exposed influences the properties of a light signal travelling throughout the fiber.
