Laser backword Scattering Two-Dimensional Imaging Simulating of Lambertian Cone

二维成像又叫平面成像,能反映目标的形状和材料特性,对于目标的识别具有重要的意义。本文研究的是朗伯圆锥体激光后向散射二维成像。利用朗伯体散射亮度与方向无关的性质来实现算法的设计,推导出朗伯圆锥的激光后向散射光强的表达式。利用C语言实现程序设计,把成像的数据保存为二进制文件,并用二进制读取软件读取数据文件,实现仿真图片的查看,分析了分辨率和激光入射方向对成像的影响,从给出的结果看出本文设计的算法能够实现朗伯圆锥激光后向二维散射成像。

Two-dimensional imaging is also called planar imaging,it can reflect the shape and material properties of the targets,thus being of great significance to target recognition.This thesis is about laser backword two-dimensional scattering imaging of Lambertian Cone simulating.This property of Lambertian is used to achieve the design of algorithms and then get the expression of Lambertian Cone scattering of laser light intensity.In this thesis,language C programming is used to save the image data as binary files,and the data file also could be read by Binary reading software.Then,the examination of simulation pictures is realized and the impact of the resolution,and the laser incident direction on imaging is analyzed.The results of this analysis show that the algorithm designed in this thesis can achieve laser backword scattering two-dimensional imaging of Lambertian Cone.
