【摘要】 从格林函数展开的角度,简要推导了Fourier衍射定理,给出目标函数与接收散射场的频域对应关系,在此基础上分析了传输和反射两种工作模式下衍射成像系统的成像特性,以及有限孔径对成像的影响。更多还原

【Abstract】 The Fourier diffraction theorem is derived briefly with decomposing the Green’s function,and the expression relates the 2-D Fourier transform of the object to the 1-D Fourier transform of the received field is given.Then the imaging quality of transmission mode and reflection mode of diffraction tomography imaging systems is analyzed.The effect of the finitesize aperture is also included.更多还原
