Abstract

为了使光谱仪能同时兼顾宽吸收光谱范围和高光谱分辨率两种特性，搭建了一台近红外虚像相位阵列光谱仪，单帧谱宽约为25 nm（140 cm-1），光谱分辨率为4.5 pm（0.024 cm-1），结合改进的旋转光栅结构，实现了1.26~1.50 μm的宽光谱检测。使用超连续光源及光学吸收多通池，在1.43~1.45 μm处，以CO2为例开展了宽带高分辨光谱测量技术研究，使用图像增强算法提高了弱吸收的光谱提取精度，考虑光谱仪的仪器展宽进而提升了气体参数反演准确度。实测光谱与理论光谱的对比结果验证了系统测量的准确性与可靠性。

期刊介绍： Researching is owned by Chinese Laser Press (CLP), which is established by Shanghai Institute of Optics and Fine Mechanics and Chinese Optical Society in 2009. Nowadays, CLP publishes 11 journals and manages three online platforms. Journal publishing activities include both traditional and digital models, and the first journal can be traced back to 1964. The CLP Online Library includes the CLP journals and partnered ones in China, and provides literature and intelligence services for users. The product platform, named as OEShow, connects sellers and buyers of optoelectronics products. Researching (formerly known as The CLP Publishing) is featured with stable operation and leading technology, collects CLP journals and partnered optics and photonics journals, and provides readers an optical publishing platform with global influence. CLP is on the way of building a modern publishing group combining traditional business and digital publishing.
