A simple and convenient method of diffuse reflection holography;

In order to improve the analysis efficiency, this paper studies the method of analyzing the composition of milk by using nearinfrared diffuse reflection spectroscopy and discusses the propagation of the light in the milk and some relevant measuring methods.

Ceramic materials have the advantages of good chemical stability,high-temperature resistance,size stability and light diffuse reflection.

The macro fractal characterization of the rough surface with low emissivity and high diffuse reflectance is analyzed by DFBIR model, and the macro fractal dimension is calculated by using SEM topography and graphic processing system S600.

This work has two objects:one is to expand the functions of infrared spectrophotometers so as to achieve the measurement of infrared diffuse reflectance at low cost;the other is to complement the means for measuring the infrared diffuse reflectance in the waveband from 2.

This paper introduces a method of the measuring for material diffuse reflectance by integrating sphere, hereby a practical instrument is designed.

This paper presents a rapid method for the characterization of sulphonated condensationpolymerized products of phenolphthalein and dichlorodiphenylsulfone (PDC) membrane by using infrared attenuated total reflection (IRATR) and diffuse reflectance (DR) spectroscopy.

The supported group VIII metal catalysts used in the methanation of carbon dioxide are studied by ultraviolet visible spectroscopy of solid diffuse reflectance.

The steady-state expression of local diffuse reflectance from surface of biological tissue is deduced from diffusion theory.

The measuring system for diffuse reflectivity was used on a two stage light gas gun and the diffuse reflectivity R b′ of (82±1)μm roughness tungsten target to incident laser was studied under 165GPa shock compression.
