Abstract

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
