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).

状态监测在许多领域中是必不可少的，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各样的参数，包括应变、温度、湿度和振动，并且非常适合于状态监测，特别是因为它们可以在诸如高温或剧毒和腐蚀性环境等恶劣条件下工作。 全球光纤传感器市场预计到2024年将达到52亿美元，到2028年将达到84.7亿美元。近年来，传感需求已经显著发展，许多应用需要能够实时监控多个点/通道和多个参数。 该项目代表了L. Chen/麦吉尔University和QPS Photronics合作开发了一个基于光频梳光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学检测。 成功的结果将为QPS提供知识和新技术，这些新技术将增强其传感解决方案，以支持实时多点/通道和多参数传感;反过来，这些新功能将使他们具有竞争优势，以满足现有和新客户的需求。 HQP的培训将为他们提供解决复杂问题的机会，进行批判性分析，并发展对广泛的光子学领域非常有价值的特定技术技能，例如，在诸如EXFO，O/E Land Inc.，MPB通信公司和OZ光学公司（渥太华，安大略省）。
