Refractive index dispersion measurement on nonlinear optical polymer using V-prism refractometer

Synthesis of PVA/CeO2 Based Nanocomposites with Tuned Refractive Index and Reduced Absorption Edge: Structural and Optical Studies

“…Thus, a deep understanding of this property is of great importance to evaluate efficient solar cells [ 47 ]. It is well-known that a high refractive index is requested for organic solar cells at a large scale [ 48 , 49 , 50 , 51 ]. In the present work, the obtained refractive index for PVA by ion incorporation is relatively higher than reported throughout the literature [ 49 ].…”

“…In the present work, the obtained refractive index for PVA by ion incorporation is relatively higher than reported throughout the literature [ 49 ]. The broad dispersion of n for PVA by ion incorporation is more significant than that reported by Shi et al for nonlinear optical (NLO) polymers, polyetherketone (PEK-c) [ 50 ]. This is a vital material for the large-scale applications of integrated-optic devices, such as electro-optic modulators and switches.…”

Smartphone-based system for measuring liquid refractive index

“…The basic principle of geometric optics method is the refraction law of light, which converts the measurement of refractive index into the measurement of angle. Such measurement methods mainly include Abbe method [4], V-prism method [5] and minimum deviation angle method [6]. The core idea of the wave optics measurement method is that the phase difference of coherent light is related to the refractive index, and the refractive index is calculated by measuring the phase difference based on interference effect [7,8].…”

Measurement of liquid refractive index based on electrically tunable lens

“…The wave optics method can realize the measurement of liquid refractive index through interference effects [6][7][8] and diffraction effects [9]. The basic principle of geometric optics method is the refraction law of light, which converts the measurement of refractive index into the measurement of angle [10][11][12], speckle in-plane displacement [13], focal plane position [14], and laser beam displacement [15], etc. Most of methods [13,15] use the imaging characteristics of parallel plates to measure the displacement.…”
