Research On Spectral Imaging Device Based On Galvanometer

With the progress of society,China has made rapid development in the field of optical technology and detection technology of optical signals.As two branches of traditional optical technology,imaging technology and spectroscopy technology play different roles.Obtaining the relevant image information of the target to be tested through imaging technology helps us to study its spatial structure;obtaining the relevant spectral information of the target to be tested through spectroscopy technology helps us to study its physical and chemical properties.Facing more and more complicated problems in modern society,it is not difficult to imagine that it is an irreversible trend to combine the spectral technology and imaging technology for comprehensive application.Hyperspectral imaging technology simultaneously obtains the spectral image information and spatial imaging information of the target object to be measured,which can help us better understand the characteristics of the target object to be measured.After acquisition,a grayscale image can be obtained in each very narrow band,and a series of grayscale images are combined to form the final hyperspectral image.In order to better understand the characteristics of hyperspectral images,the three-dimensional data information presented by hyperspectral images,where the two-dimensional information is consistent with the two-dimensional information captured by our eyes or cameras,reflects the morphological structure of the target object,but the hyperspectral image The third-dimensional spectral information can be used as one of the unique feature standards for distinguishing target objects,which will be introduced in the subsequent application of imaging spectroscopy technology.If the object is divided into many pixels horizontally and vertically,then each pixel has a unique spectral curve corresponding to it.It can be concluded that the hyperspectral image can display the spectral information of different pixels while displaying the spatial imaging information of the target object,so imaging spectroscopy technology has received much attention in the field of information data acquisition in recent years.At the same time,under the premise of continuous progress of society and science and technology,imaging spectroscopy technology has been applied in various fields,playing an increasingly important role for the development of human society.Imaging spectroscopy technology also involves the comprehensive application of multiple disciplines,which has great research value for us.In this paper,an imaging spectroscopic device based on galvanometer is designed,which is innovatively designed in the scanning mode and control mode of the device to achieve the purpose of spectral imaging,and the device designed and studied has a simple structure and many channels for easy observation The advantage of changing spectral intensity.In this article,first of all,the research is carried out according to the development trend of imaging spectroscopy technology,and the research value and significance of imaging spectroscopy technology are proposed.Furthermore,to explain and compare imaging spectroscopic devices with different principles,let us have a further understanding of their working principles.Then,the hardware module and the required software system of the imaging spectroscopic device studied in this paper are introduced in detail.The hardware module includes the galvanometer combination,ELVIS II + driver board,FX2000 spectrometer and galvanometer lens;Completion,galvanometer scanning algorithm,interpretation of system errors,etc.Specify the implementation process on the basis of clear principles.Finally,the experimental design and actual data acquisition are carried out for the imaging spectroscopic device designed and implemented in this paper,and the research contents of this paper are summarized and summarized.It is concluded through experiments that the purpose of distinguishing true and false plants can be achieved through imaging spectroscopy.At the same time,the reasons for the low pixels of the imaging pictures present in the experiment at this stage are analyzed,and solutions are proposed.
