摘要
研究了成像信道斜程因子、大气湍流的非科尔莫戈罗夫功率谱指数、光源空间相干性(高斯谢尔束)和光源横向尺寸对隐影成像的影响。研究中运用光学相干理论、广义惠更斯菲涅耳原理和非科尔莫戈罗夫湍流模型,分析并建立了斜程湍流Z倾斜像差校正大气信道中高斯谢尔束无透镜隐影成像理论模型。通过此模型的数值计算得出了待成像物体越靠近照明光源,所成隐影像的质量越高;照明光源的尺寸过小会造成隐影像质量的下降和物体被非相干光照明时的成像质量要差于部分相干光照明时的隐影像质量。
Abstract
Imaging channel slant factor, the atmospheric turbulence of power spectral index of non-Kolmogorov, the light source spatial coherence (Gaussian-Schell beams) and lateral dimensions of the light source of the ghost imaging have been studied. Based on the optical coherent theory, the extended Huygens-Fresnel pricinple and the turbulence model of non-Kolmogorov, Z-tilt aberration correction of the atmospheric channel of slant channels turbulence of the theoretical models of ghost imaging with Gaussian-Schell beams have been analyzed and derived. By the numerical computations of the model, the result shows that the nearer the object is to illuminant plane, the better the quality of ghost imaging is. The undersized illumination light source will cause the quality decline of ghost imaging and the image quality of the object illuminated by the incoherent light are worse than that of illuminated by partially coherent light.
