An acoustic method for measurement of the effective temperature and refractive index of air along a laser beam path is described. The method can be used to improve the accuracy of interferometric length measurements outside the best laboratories, and even in severe environmental conditions. The ...
Influence of Temperature on Refractive Index Determination So what is the relationship between refractive index determination and temperature? First, we need to understand the effect of temperature on a liquid sample. Temperature influences the space in which atoms fit together ...
On The Refractive Index of Soot at Flame Temperature Data of the optical constants of soot at flame temperature are presented for the visible and infrared regions (0.4-5 μm). Both real and imaginary parts of... ZG Habib,P Vervisch - 《Combustion Science & Technology》 被引量: 84发表: ...

A standard case of application of optical flow visualization is the air flow around a projectile or aerodynamic shape flying at high velocity (Fig. 6). This application to experimental ballistic studies can be traced back to the middle of the 19th century when the methods had been invented in...
The refractive index of air-hydrate crystals found in a deep Antarctic ice sheet was measured for the first time, as far as we know, using a Mach-Zehnder interferometer. A small difference between the refractive indices of the air-hydrate crystals and the matrix ice crystal was measured by ...

The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical soda-lime glass has a refractive index of 1.5, which means that
of the structure. Perfect matched layer (PML) is used to design the refractive index of air, the relative dielectric constant of silver, and the structural parameters. The fine triangular meshes are selected to ensure the perfect segmentation of the simulation area, and the maximum triangular ...
To ensure the seawater refractive index’s measuring range, a position-sensitive detector with a photosensitive surface size of 4 mm × 4 mm was selected; whereas, to reduce the working environment’s temperature variation, we partitioned the measurement system. To validate the testing error range...
