Development and Application of Portable Short Wave NIR Corn Component Analyzer 便携式短波近红外漫透射玉米成分快速分析仪的研制和应用
The two 1/ 4 wave plates, photoelastic modulator and analyzer are placed behind the index grating to realize the modulation of the Moire signal with high frequency. 两块1/4波片、光弹调制器和检偏器置于探测光栅之后,实现对莫尔信号的高频调制。
The polarization modulator is composed of a polarizer, a Savart plate, two 1/ 4 wave plates, a photoelastic modulator and an analyzer. 该偏振调制器主要由起偏器、萨伐尔板、两块1/4波片、光弹调制器和检偏器构成。
Virtual Instrument technology is used in the design of the general wave recorder, impact analyzer, spectrum analyzer, stable and transient signal analyzer and so on. 系统软件使用虚拟仪器技术,设计了通用数据记录仪、浪涌分析仪、频谱分析仪、稳态和瞬态信号分析仪等多种虚拟仪器。
On the basis of the interference theory, by decomposing the single wave beam, the transmission of polarized light passing through a rotating Taylor analyzer is calculated. 采用光束分割法及光的干涉原理,对线偏振激光通过泰勒(Taylor)偏光棱镜后的透射比变化情况进行了分析。
