DEVELOPMENT OF TRANSPARENT NONIMAGING DAYLIGHTING DEVICE USING REFRACTION AND TOTAL REFLECTION

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Reflection, Refraction and the Prism

Huygens’ principle can be used to determine various experimentally verifiable and predictable behavior of the path of light through any optical system. However, as seen in the chapter on Light, the Huygens wavefront construction can be become complicated, especially in systems with a large number of optical components. A simpler approach to track the behavior of light is based on the propagatio...

Development of a cryogenic index of refraction measuring device

Refraction and reflection of diffusion fronts.

Diffusion waves form the basis of several measurement technologies in materials science as well as in biological systems. They are, however, so heavily damped that their observation is a real challenge to the experimentalist. We show that accurate information about the refraction-like and reflection-like behavior of diffusion waves can be obtained by studying diffusion fronts. For this we use h...

Wave Reflection and Refraction at the Interface of Triclinic and Liquid Medium

A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...
