Optical Sensing Limited (OSL) was established in 2011 by the founding partners / shareholders. The mission is to provide intelligence based monitoring systems to organizations / operators who operate systems of power, energy, HVAC (Heating, Ventilation & Air Conditioning), transportation and hydrology/geology. The objectives of the monitoring system are to protect their asset investment; promote green environment; and to enhance service quality.
OSL launched the first solution in July 2013. The first solution is a Distributed Temperature Sensing (DTS) system. The DTS system makes use of an ordinary fibre optic cable to sense and measure the temperature of the host system to which a sensor fibre optic cable has been attached. The whole fibre optic cable is a sensor thereby providing continuous monitoring contrasted with discrete sensors.
DTS is based on Raman back scattering. Raman back scattering was discovered by Professor Raman in 1983 at University of Southampton, UK.
OSL obtained patents from Chinese and HKSAR Governments on the system software developments. OSL has also developed advanced application software for analysis of temperature profiles to effectively identify abnormal operating conditions of host systems.
The DTS system can greatly enhance service quality and improve environmental quality as well as protection of valuable assets.
