Optical and Fiber Sensors Group

Sensors Group is working in the areas of optical sensors using bulk optical components and interferometry, optical fiber sensors, fiber Bragg grating (FBG) fabrication and its applications. FBGs based sensors have huge potential worldwide in optical sensor and communication industry. These sensor systems are light weight, robust, versatile, competitive in cost, and immune to electromagnetic interference. Some of the application areas of the FBG sensors are fatigue, vibration, sound & ultrasound, creep, temperature, pressure detection, structural health monitoring and many others.
