Description

technical field [0001] The invention relates to a hyperspectral imaging technology, in particular to a novel computational hyperspectral imaging technology. Background technique [0002] The principle exploration and research of new optical information acquisition technology has always been an important content in the development of optical technology. Spectral imaging technology is a new type of detection technology integrating optics, spectroscopy, precision machinery, electronic technology and computer technology. While obtaining the spectral characteristic curve of the target, it can also obtain the geometric shape information of the target. On the other hand, the spectral imaging technology combined with polarization and dynamic time change information can also obtain the morphological characteristics and dynamic characteristics of the target well. Therefore, optical multi-dimensional imaging based on the integration of time, space, spectrum, polarization and other inf...

Problems solved by technology

[0009] For the traditional imaging system, there are often technical bottlenecks such as the difficulty of system engineering implementation, the difficulty of hardware technology, the pressure of massive data transmission, the large amount of data redundancy, and the low data utilization rate.

For example, the current technical system is limited by the difficulty of realizing a large-aperture long-focus spectral imaging system, the difficulty of manufacturing a large area array detector with high frame rate, the constraints of low incident energy, and the difficulty of multi-dimensional imaging engineering, which does not have engineering feasibility. Energy constraints also lead to a low signal-to-noise ratio. At the same time, the problem of excessive data volume brought about by multi-dimensional imaging also affects the collection, transmission and processing of data.

[0010] In addition, the existing technology still has design problems such as lack of intelligence and incomplete information acquisition.

For example, it is impossible to perform intelligent perception based on the difference in target characteristics, to realize intelligent identification when information is obtained, and to adjust the acquisition system according to the feedback of the perception results; moreover, the method of obtaining information is single, and does not take into account the target space, spectrum, time, Consistent acquisition of multi-dimensional information such as polarization
