    Abstract: An aerodynamic optical effect correction and identification integrated real-time processing system, comprising an FPGA module, a multi-core main processor DSP, a plurality of auxiliary processors ASICs and an infrared image non-uniformity correction system-on-chip (SoC). By means of the system, full-image thermal radiation correction, denoising, transmission effect correction and target detection processes of an aerodynamic optical effect degradation image are achieved. Correspondingly, provided is the corresponding method. The system effectively solves the problem of aerodynamic optical effect and the problem of the requirement for a short detection time interval of the processor in an aircraft flying at a high speed; due to the adoption of the independently researched and developed ASIC, the real-time property of the whole system is greatly improved; all tasks are rationally distributed and a multi-core parallel mode is adopted, so the image processing time is greatly shortened; and meanwhile, the FPGA module connects all units to form a closed-loop system, so that the system stability is further improved.

    Abstract: The present invention belongs to the technical field of elemental analysis, and more particularly, relates to a dynamic calibration method for echelle spectrometer in laser-induced breakdown spectroscopy, comprising: S1: collecting a standard light source by using an echelle spectrometer; S2: in combination with a calibration function, calculating a pixel position coordinate ({circumflex over (x)}, ŷ) corresponding to a spectral wavelength ŵ; S3: performing dynamic searching and filtering near the pixel position coordinate ({circumflex over (x)}, ŷ) to obtain a set D of all pixel position coordinates, and adjusting all original intensity values in the set D to obtain intensity values F(Ix,y), and S4: calculating a spectral line intensity value after dynamic calibration by summing the adjusted intensity values F(Ix,y), thereby completing dynamic calibration of the result of the echelle spectrometer. The method in the present invention can overcome the shortcoming, i.e., the existing echelle spectrometer is only calibrated before measurement without solving the spectral line drift during use, increasing the absolute intensity of the wavelength and reducing the detection limit of the quantitative analysis, as well as improving the precision of the quantitative analysis of an element to be analyzed.

    Abstract: The invention discloses a method for generating a row transposed architecture based on a two-dimensional FFT processor, comprising the following characteristic: the FFT processor includes an on-chip row transposition memory for storing an image row transposition result. When the size of the row transposition result exceeds the capacity of the on-chip memory, the first 2k data of a row of the two-dimensional array after row transformation is written into the on-chip row transposition memory, the remaining data is written into the off-chip SDRAM, and k is acquired through calculation according to the row transposition result and the capacity of the on-chip row transposition memory. The on-chip memory is divided into two memories A and B used for storing the row transposition partial result and temporarily storing data read from off-chip SDRAM. When data is read from the memory A or B column by column for FFT column transposition, SDRAM is accessed in a row burst manner and data is written into the empty memory A or B alternately, and finally SDRAM is empty through repetitive ping-pong switching between the memories A and B. The row transposed architecture is capable of substantially reducing cross-line accessing frequency of SDRAM and improving two-dimensional FFT execution speed.
