Optical frequency combs for multichannel optical vibration sensing

Condition monitoring is essential in numerous fields, e.g., structural engineering, environmental engineering, and power engineering. Fiber optic sensors can measure a wide variety of parameters including strain, temperature, humidity, and vibration and are well suited for condition monitoring, especially since they can operate under harsh conditions such as high temperature or in highly toxic and corrosive environments. The global fiber optic sensor market is projected to reach $5.20B US by 2024 and $8.47B US by 2028. In recent years, sensing needs have evolved significantly and many applications require the ability to monitor multiple points/channels and multiple parameters in real-time. This project represents a strategic collaboration between L. Chen/McGill University and QPS Photronics to develop a comprehensive optical vibration sensing platform based on optical frequency comb sources that can be used for multiple applications, ioncluding condition monitoring in power transformers as well as for acoustic detection for underwater imaging. A successful outcome will provide QPS with intellectual knowledge and access to new technologies that will enhance their sensing solutions to support real-time multi-point/channel and multi-parameter sensing; in turn, these new capabilities will give them a competitive advantage to address the needs of existing and new clients. Training of HQP will provide them with opportunities to solve complex problems, perform critical analysis, and develop specific technical skills that are highly valuable to the broad photonics sector, e.g., in companies such as and employers including optical component and instrumentation suppliers such as EXFO, O/E Land Inc., MPB Communications, and OZ Optics (Ottawa, ON).
