摘要

摘要: 根据高精度近红外数据采集系统的要求，设计了3套数据采集系统。前两套数据采集系统是针对不同的近红外探测器的特性而设计的，能满足近红外数据采集的高精度要求。最后一套数据采集系统采用直接电流模数转换的方法，不仅简化了采集系统的电路结构，也可以为近红外光谱测量系统的设计提供参考。为近红外探测器数据采集系统提供了3种不同的设计方案，并搭建了模块进行了测试分析，在实践中得出了各种电路的优缺点和应用环境，对工程人员具有一定的参考价值。

Abstract: Based on the requirement of high-precision near-infrared data acquisition system and the characteristics of infrared detectors, two different types of data acquisition systems are designed, which can achieve the expected accuracy. In addition, a direct current analog-to-digital acquisition system is designed, which simplifies the circuit structure of the acquisition system and provides a reference for the design of near-infrared spectrum measurement system. Three different designs of data acquisition system for near-infrared detector are provided, and relevant analysis circuit is implemented to analyze each circuit's feature and its application environment.
