紫外可见分光光度计数据采集的单片机实现

Single Chip Computer Based Implementation of Data Acquisition for Infra-violet Visible Light Spectrometer

双光束分光光度计在分子吸收光谱测量中起着十分重要的作用。本文提出一种以ATMEL89C51单片机为核心的数据采集系统,有效地实现了分光光度计的数据采集与存储,同时,在计算机上实时显示吸收光谱的曲线,满足数据分析与处理的需要。

Spectrometer with dual light beams takes significant role in molecular absorption spectrum measurement. A data acquisition system with AT- MEL89C51 single chip computer as the kernel is introduced in this paper. The system effectively implements data acquisition and data storage for spectrometer, meanwhile, the absorption spectrum curves are display in real time on computer. The requirements of data analysis and data processing are satisfied.
