Optical frequency combs for multichannel optical vibration sensing

状态监测在许多领域都是必不可少的，例如结构工程、环境工程和动力工程。光纤传感器可以测量各种参数，包括应变、温度、湿度和振动，非常适合状态监测，特别是因为它们可以在高温等恶劣条件下或在剧毒和腐蚀性环境中工作。预计到2024年，全球光纤传感器市场将达到52亿美元，到2028年，将达到84.7亿美元。近年来，传感需求发生了显著变化，许多应用需要实时监测多个点/通道和多个参数的能力。该项目代表了L.Chen/McGill大学和QPS光电子公司之间的战略合作，以开发基于光频梳源的综合光学振动传感平台，该平台可用于多种应用，包括电力变压器的状态监测以及水下成像的声检测。成功的结果将为QP提供智力知识和获得新技术的机会，这些新技术将增强他们的传感解决方案，以支持实时多点/通道和多参数传感；反过来，这些新能力将使他们获得竞争优势，以满足现有和新客户的需求。HQP培训将为他们提供解决复杂问题、执行关键分析和发展对广泛的光电子行业非常有价值的特定技术技能的机会，例如，在EXFO、O/E Land Inc.、MPB Communications和OZ Optics(渥太华，安大略省)等公司和雇主中，包括光学元件和仪器供应商。

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).
