摘要
研制基于线性渐变滤光片和InGaAs焦平面的微型化物联网节点,实现长波近红外光谱数据的采集和无线传输,针对节点的波长范围、分辨率、波长准确性和波长稳定性等参数指标开展性能研究实验.实验结果表明,节点的波长范围为950~1700 nm,光谱分辨率随波长增加而增大,约为峰值波长的1%,与滤光片特性相符,波长准确性优于1.3 nm,波长重复性优于0.1 nm,可以满足物联网中的近红外光谱分析应用需求.
Abstract
A compact IOT node based on linear variable filter and InGaAs focal plane array was presented. The long-wavelength near-infrared spectral data can be collected and transferred with wireless communication method. Performance experiments were carried out to test the parameters of the node, such as wavelength range, spectral resolution, wavelength accuracy and stability. Experimental results demonstrate that the wavelength range is from 950nm to 1700 nm, and the spectral resolution is approximately 1% of peak wavelength. The wavelength accuracy and wavelength stability are less than 1.3 nm and 0.1 nm respectively. The proposed node can meet the demand of near infrared spectral analysis in IOT applications.
