Web299K views 6 years ago Physics. How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand the physics of light. WebOct 31, 2013 · An intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings is proposed and experimentally demonstrated. The sensor is formed by a tilted-fiber Bragg grating (TFBG) coated by magnetic fluid (MF) and cascaded by a chirped-fiber Bragg grating (CFBG). Transmission of the TFBG is modulated by refractive index of …
