[ Instrument Network Instrument Development ] Recently, the Associate Researcher of the Atmospheric Optical Research Center of Anguang Institute and his research team made a series of new progress in related imaging.
Object information acquired at different compression sampling rates. Sinogram is the Radon spectrum of the object, and FBP is the image acquired by the backward projection filtering algorithm.
The most important source of information in human production and life is the image, and imaging detection is a major way to obtain images. In recent years, a single-pixel imaging technology that is fundamentally different from traditional imaging technology in imaging detection mechanism has attracted more and more attention because of its ability to break through the limitations of traditional imaging fields. Compared with the traditional scanning single-pixel imaging technology using the local single-point sampling method, the imaging technique uses the global sampling method, that is, all the information of the object participates in the sampling in each sampling process, but the technique uses the spatio-temporal transformation light field. The object is illuminated and the corresponding calculation algorithm is used to obtain the object information.
The Radon spectrum of objects is an integral transform technique widely used in the field of non-destructive imaging. It has been widely used in damage-free detection. Moreover, due to the specificity of the Radon spectrum, it has also been widely used in the field of classification and recognition of object feature details and moving object tracking.
At the Center for Atmospheric Optics, Anguang Institute of Optics, Dong Feng, associate researcher and his research team proposed a space-time transformed light field based on the Radon model. The Radon spectrum of the object was acquired by single-pixel imaging technology, and the backward projection operation of the Radon spectrum was performed. Obtained an image of the object. Related research results are published in the latest issue of Optics Express [29 (10), 2019]. This method is used to achieve moving object tracking with 177fps resolution of 256×256 pixels. The corresponding research results are published in Optics Communications [440(1), 2019]. At the same time, single-pixel imaging technology for fast Fourier spectrum acquisition was carried out, and related research results were published in Optics Express [26 (13), 2018].
The above research work was funded by the National Natural Science Foundation of China and the National Defense Innovation Fund of the Chinese Academy of Sciences.
