【摘要】 我们利用正交偏振方法将傅里叶谱的实部和虚部分开,从而测定了一维和二维傅里叶谱的相位。文中报道了位移狭缝和位移方孔傅里叶谱相位的测量结果,它们与用位移量计算出的相位值符合很好,因此证实了该方法的可靠性。在此基础上我们还考察了其它二维二进制图形傅里叶谱的实部和虚部。更多还原

【Abstract】 By using a coherent optical information processing system with two orthogonal polarization channels we have measured the Fourier phases experimentally for one and two dimensional real objects. For a shifted slit and a shifted square, the Fourier phase values measured by experiment are in agreement with the calculated phase values quite well. Another object is a binary alphabet, the real and imaginary part of its Fourier spectrum has been investigated.更多还原
