reference standard
相关语句
  参考标准
    Traditional methods need a reference standard and there is muchuncertainty because either a standard light source or a separate reference detector isrequired.
    但是传统的标定方法都需要一个参考标准,不是标准的光源就是另一个标准探测器,具有一定的不确定度。
短句来源
    The absolute bidirectional reflectance factor of a standard sample made by sintered polyte trafluoroethylene (PTFE) is determined in the range of 400-2500 nm. The reference standard is direction hemisphere reflectance factor transferred by the National Institute of Measurement.

This article discribes a comparative method for experimental determination of SHG coefficients of some crystals. With the d36KDP as a reference standard, we measured both d36KDP and d31BNN, d32BNN of several samples of BNN crystal. Their results show that the coefficient d32RNN is sensitively related to the stoichiometric composition of BNN crystal. Some discussions concerning the nonlinear optical properties of BNN crystal are also presented.

NBS (U. S. National Bureau of Standards) maintains a set of electrically calibrated calorimeters designed and built specifically for laser energy measurement. These calorimeters are used as national reference standards for the calibration of laser power and energy meters. Using these calorimeters, NBS offer laser measurement services for variety of laser wavelengths and power and energy ranges, Present situation of measurements are described in this paper.

A method for calibrating spectral bidirectional reflectance in any illumination and viewing geometrics is proposed. The absolute bidirectional reflectance factor of a standard sample made by sintered polyte trafluoroethylene (PTFE) is determined in the range of 400-2500 nm.

在光谱光度计的校准中,需要在特定的入射和接收的几何条件下进行。在一些情况,校准的几何条件和光谱区受到了限制,因此有必要建立一种可适用于任意几何条件下和更宽光谱区的校准方法。本文介绍了一种校准光谱双向反射的方法,可适用于各种入射和接收的几何条件。从400~2500nm的光谱范围内,确定烧结的聚四氟乙烯标准样品的绝对双向反射系数,参考标准是通过国家计量院传递的方向—半球反射系数。测量用的双向反射分布函数(BRDF)测定仪可以全自动地测量几乎所有可能的几何条件下的绝对双向反射系数
