The invention provides a combined-type anti-counterfeiting mark based on a same ID. The combined-type anti-counterfeiting mark is composed of a quick response code and a raster graph. The quick response code and the raster graph all comprise the same ID number extracted from an ID number database during a generating process. The method for generating the combined-type anti-counterfeiting mark comprises the steps that by using a quick response code generator, the ID number, parameter information of the quick response code, plaintext information and preset ciphertext information memory area are converted into the quick response code, wherein the ID number, the parameter information of the quick response code and the plaintext information are extracted from the ID number database; by using a raster graph generator, the raster graph is generated by the ID number which is same as the quick response code. The device for generating the combined-type anti-counterfeiting mark comprises the quick response code generator and the raster graph pattern generator. The quick response code and the raster graph comprise the same ID number, and therefore the quick response code and the raster graph have relevancy, due to the fact that quick response code can only be recognized and read through dedicated equipment, the raster graph cannot be recognized once again after being copied and scanned, and therefore the high level anti-counterfeiting performance is achieved.

The invention relates to a phase screen simulation method of short distance transmission of light in underwater turbulent flow, and belongs to the field of underwater target detection. The phase screen simulation method of short distance transmission of light in underwater turbulent flow is provided for solving the shortcomings that a phase screen model cannot really simulate the properties of turbulent flow as the correlation between phase screens in multiple layers of phase screens is not considered in the prior art. The method comprises the following steps: inputting an initial image; calculating a pixel value of a current reference point by using a reference point with a known value; calculating a relative pixel difference; calculating an absolute value of the reference point; repeating the above process until left and right reference points of all phase screens are calculated; generating multiple processes, wherein each process contains one framework; simultaneously calculating the absolute value of each point in the framework by using a parallel calculation method; repeating the process of calculating the absolute value of each point of each process; and repeating the above steps until all points are calculated. The phase screen simulation method provided by the invention is suitable for the analogue simulation of a transmission model of light in underwater turbulent flow.
