Numerical Simulation of Light Transmission through Optical Fibers: Linear and Nonlinear

The unique atrium space design brings different visual perception to people, and rational atrium structure has a good influence on natural lighting and energy consumption. The lighting atrium has been widely used in public buildings. This paper aims to optimize the atrium design of public buildings. Some factors such as atrium aspect ratio, light transmission coefficient of the glass and atrium shape etc, were probed in through numerical simulation, which analyzes lighting influence of various lighting atrium forms. On this basis, this paper draws some conclusions, such as daylight factor of atrium space distribution characteristics and its relevance of atrium space geometry, proposes some optimization strategies of architectural lighting atrium, try to provide some guidance in the atrium application of public buildings.

A three-dimensional (3D) Low Temperature Cofired Ceramics (LTCC) fluidic microsystem integrated with an optical detection unit is presented in this article. The structure is applied to quantitative analysis of chemical compounds using colorimetric methods. The fabricated microfluidic system consists of a serpentine mixer, fluidic channels, heater, embedded temperature sensor and integrated optical fibers for detection of light transmission and/or fluorescence. A new inexpensive material for the embedded temperature sensor is described. The fluidic system is designed using computer CFD (Computational Fluid Dynamics) simulations. Fluid flow in the mixer is observed through a transparent polymer material bonded to the LTCC structure. The importance of positioning of optical fibers and their influence on the absorbance and fluorescence measurements is presented.
