Research On Micro Imaging Spectrometer Based On Cloud And Embedded WEB Double Server

Imaging spectroscopy combines imaging and spectral detection techniques to spatially image the target while also screening the spectral information of each spatial pixel to obtain a ―three-dimensional‖ data set of the target.Imaging spectroscopy is the important tools in the field of spectral analysis which has been widely used in food safety testing,medical diagnosis,agricultural and sideline industries,materials and other related fields.At present,the miniaturization and portability of the imaging spectrometer has become a new research direction and development trend,and new requirements have been put forward for the principle design,manufacturing process,and performance indicators of the imaging spectrometer.In order to adapt to the development trend of imaging spectrometer,this paper designs and implements a miniature imaging spectrometer system based on cloud and embedded WEB dual server.The main work includes:1.Based on the hardware structure of the miniaturized imaging spectrometer host developed in this project,the embedded Linux operating system,embedded WEB service BOA and embedded SQLite database are transplanted to realize authentication,mosaic array data acquisition,video preview,focusing and other related functions.2.Use Tencent Cloud to build a dedicated cloud server for network environment configuration and domain name configuration.Set up a Django framework service and a MySQL database on the cloud server to provide an operating environment for spectral data processing.3.Analyze the "three-dimensional" data set of imaging spectrum,realize the separation of image dimensions on the cloud server,complete the acquisition of spectral information in fixed-element pixel dimensions,optimize the preprocessing algorithm of traditional imaging spectrum,reduce system overhead,and achieve real-time display the effect of processing the result.4.According to the characteristics of the dual-server of this project,it is designed to realize the dynamic interaction between the user and the two servers,and solve the problem of cross-domain access of web pages.The dual-server miniature imaging spectrometer scheme implemented in this paper realizes the collection and display of mosaic array spectrum data,completes the analysis and processing of imaging spectrum data on the cloud server,enhances the portability and flexibility of the miniature imaging spectrometer,and expands its application range.
