Roy. Soc.,59, p. 198, 1896 Nobel Prize 1904 Rayleigh’s Interferometer is used to measure the refractive index of a gas. His refractometer is based on Young’s double slit interferometer.
WebThe design and operation of the conventional Rayleigh interferometer generally follow those of figure 1. 12 Light from slit S is collimated by lens L 0 falling on the two slits S 1 , S 2 . WebIn order to further improve the performance of Rayleigh Interferometer (RI) used for measurement of gas/liquid index, a Dispersed Rayleigh Interferometer (DRI), which uses a broadband source and disperses monochromatic interference pattern perpendicular to the direction of baseline, is proposed to expand measurement range and to acquire optical …
WebA novel distributed sensing technique based on reflectometry is proposed. The technique uses the interference of the light waves backscattered within the resolution range of a reflectometer to detect the optical path changes in a single-mode fiber. Experimental results are presented, and practical realization of an intrusion detector that employs this … WebApr 9, 2024 · In 1896, Lord Rayleigh (J.W. Strutt, 1842–1919) applied the method of two-beam interferometry for measuring refractive indices of gaseous argon and helium (which are very low) . In the Rayleigh two-beam interferometer, a light beam is split (using a special diaphragm) into two beams, which pass through an optical medium and then merge again.
