The speed of all electromagnetic radiation in vacuum is the same, approximately 3×108 meters per second, and is denoted by c. Therefore, if v is the phase velocity of radiation of a specific frequency in a specific material, the refractive index is given by or inversely This number is...
These results indicate that combining the fundamental optical properties of tissues denoted by their refractive index with morphological dilation may open routes to define supporting procedures during breast-conserving surgeries.doi:10.1038/s41598-021-85853-8Quentin Cassar...
By using FDTD method, we characterize the performance of the proposed RI sensor utilizing parameters including RI range and sensing resolution, sensitivity (denoted by symbol S), figure of merit (FoM), quality factor (Q) and dephasing time. Then we listed the performance between the RI sensor ...
Step-by-Step Solution 1. Definition of Refractive Index: - The refractive index (often denoted as n or μ) is defined as the ratio of the speed of light in a vacuum to the speed of light in a given medium. - Mathematically, it can be expressed as: n=cv where: - n = refractive...
27, a refractive index distribution lens 11 has an effective portion 12. The effective portion 12 is located in the center of the refractive index distribution lens 11 and has a diameter, which is denoted by De. Aberrations are tolerated in the effective portion 12. A peripheral portion 13 ...
After the probe is reflected by the sample, the reflected light propagates to the CMOS detector placed at a distance d away from the sample. The resolution and the pixel size of the image plane are denoted as M× N and p, respectively. Figure 2. (A) Layout of the optical measurement ...
The transmittance spectrum is obtained by numerical analysis using the finite element method. The results confirm that the sensing sensitivity of the refractive index of the optimised waveguide structure can achieve up to 825 nm/RIU. Whereas this structure could accurately identify the five proposed ...

PURPOSE:To extend an operating distance, and to correct satisfactorily an aberration by constituting a titled lense so that a surface of a luminous flux incident side in case of using a single lens having a refractive index gradient in the direction vertical to an optical axis by a reducing ma...
Optical or atmospheric turbulence cause scintillation or twinkling of distant light sources. The strength of this turbulence that produces scintillation is represented by the refractive-index structure parameter, which is denoted by Cn2. In particular, this parameter, Cn2reflects the optical turbulence imp...
