The question of radiometric resolution is an important one in connection with the introduction of digital systems. The number of available bits is generally given with the note that the achieved radio...
The approach utilized in the design of achromatic periods formed of two layers a high-index and a low-index is developed by combining the first two periods together. These two periods are therefore re...
We have newly developed Bi 2 O 3 -B 2 O 3 -TeO 2 glass system. This glass shows high transmittance in visible and near-IR wavelength, in spite of their high refractive index and optical nonlinearity.
采用便携式可见/近红外检测仪快速检测阿巴特、康佛伦斯和五九香梨硬度。采集洋梨漫透射光谱(500~1010nm),经二阶导数和卷积平滑处理后,分别建立偏最小二乘法和多元线性回归模型。相关系数法和遗传算法用于选择偏最小二乘法建模变量,预测均方差分别为7.780N和8.080N,相对预测误差分别为26.24%和29.71%。多元线性回归模型使用7个变量,预测均方差和相对预测误差分别为7.740...
The application of Full Counting Statistics to a Dicke super-radiant model allows us to obtain an accurate description of the number of radiated bosons in the transient regime. This includes for examp...
We examined the light transmittance characteristics and refractive indices of light-activated pit and fissure sealants. Five commercial pit and fissure sealants and human enamel were studied, along wi...
Ti-doped In2O3 thin films have been prepared on glass substrate by radio frequency (RF) sputtering with different sputtering powers (90, 120, 150, and 180 W) at 330 °C. The influence of sputtering p...
该文对薇甘菊及其所在群落内19种植物(草本和木本)的叶片透射率、反射率和光合特征指标进行了测定, 结果表明:薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近, 在各个光学特征指标与光合相关指标的相互关系中, 薇甘菊并没有表现出区别于同一群落内其它植物的特征。从平均值来看, 200-800 nm下叶片反射率和透射率由大到小依次为: 薇甘菊>草本植物>木本植物, 薇甘菊各光学植被指标(SR680、S...
The purpose of this investigation was to examine the effect of filler particle size and shape as well as filler content on light transmittance characteristics and color of experimental composite resin...
Ta-doped In2O3 transparent conductive oxide (TCO) thin films are deposited on glass substrates by radio-frequency (RF) sputtering at room-temperature. The influence of sputtering power on the struct...
We tried to construct a simple integrated tube-type pyranometer using phycoerythrin from seaweed pigment. The maximum sensitive waveband of phycoerythrin was 550nm∼560nm, and this waveband was i...
The objective of the present study was to develop a method to analyze apparent amylose content (AAC) of Japanese milled rices using near-infrared transmittance spectroscopy (NIT). Samples (n=110, vari...
The objective of this study was to develop a partial least squares regression (PLS) calibration method of maximum viscosity determination of Japanese milled rice flours using near-infrared transmittan...
We compared cv. Mochiminori as glutinous rice and cv. Koshihikari as non-glutinous rice using light transmittance photography and clarified that the maximum hollow width/grain width ratios at the holl...
The performance of partial least squares (PLS) calibration models developed using NIR and visible transmittance were examined in order to improve the accuracy of the calibration model for amylose cont...
