摘要:

作为一项新兴的过程分析技术,成像光谱技术在获得样品空间信息的同时,还为每个图像上每个像素点提供数十至数千个窄波段的光谱信息,这样任何一个波长的光谱数据都能生成一幅图像,从而实现“图谱合一”。通过对光谱、图像的分析,即可对样品的成分含量、存在状态、空间分布及动态变化进行检测。本文从成像光谱技术的原理、系统构成、数据分析方法方面进行简要介绍,并详细介绍成像光谱技术在农产品/ 食品检测中的国内外研究进展,目前的研究表明该项技术在农产品/ 食品检测中具有广阔的应用前景。

Abstract:

As a newly emerging technology for process analysis, imaging spectrometry can acquire spatial information of samples and provide thousands of spectral data points for each pixel in an image. In this way, the spectral data of each wavelength form an image and result in the syncretism of spectra and image. By analyzing corresponding spectra and images, the components, concentration, status, spatial distribution and dynamic change of samples can be detected. In this paper, technical principles, system compositions and data processing methods of imaging spectrometry are described. The research progress in the detection of agricultural products/food by imaging spectrometry is discussed. Based on the current research achievements, imaging spectrometry reveals a wide range of application prospect in the detection of agricultural products/food.

Key words: imaging spectrometry, hyper-spectral imaging, near infrared image, agricultural product, food safety
