Fiber Optic Speckle Sensor

Home / Fiber Optic Speckle Sensor

Here, we report a fiber-optic point-based sensor to measure temperature and weight based on correlated specklegrams induced by spatial multimode interference. The device is realized simply by splicing a multimode fiber (MMF) to a single-mode fiber (SMF) with a core offset. Fiber Bragg grating (FBG) sensors, a significant category within optical fiber sensors, provide solutions for quasi-distributed sensing applications but introduce complexities related to both sensor interrogation and the specialized and sometimes expensive equipment needed for grating inscription.
