经典非相干光无透镜傅里叶变换鬼像
Lensless Fourier-Transform Ghost Imaging with Classical Incoherent Light
摘要：
采用一种新的无透镜方案，用经典非相干光在菲涅耳距离上对纯振幅物体和纯相位物体进行了傅里叶变换鬼像实验研究。实验结果与相应物体的标准傅里叶变换结果吻合较好。该方案提供了一种新的途径，无像差衍射限制的3D图像与经典的非相干热光，它没有分辨率和景深的限制，基于透镜的层析成像系统。
英文摘要：
The Fourier-Transform ghost imaging of both amplitude-only and pure-phase objects was experimentally observed with classical incoherent light at Fresnel distance by a new lensless scheme. The experimental results are in good agreement with the standard Fourier-transform of the corresponding objects. This scheme provides a new route towards aberration-free diffraction-limited 3D images with classically incoherent thermal light, which have no resolution and depth-of-field limitations of lens-based tomographic systems.
