The method to record an incoherent Fourier hologram is proposed. The interference patterns in the dual channel rotational shearing interferometer are obtained as the figure of the cosine and the sine transformation in the vertical and the horizontal polarization, respectively. The proposed optical system is simple without spatial light modulators or mechanical phase shifting devices. The experiment, in which the letter "A" displayed on a liquid crystal display with a blue LED backlight was used as an object, confirms the proposed method to obtain an incoherent Fourier hologram.
提出了一种记录非相干傅里叶全息图的方法。双通道旋转剪切干涉仪中的干涉图样分别作为垂直和水平偏振下的余弦和正弦变换图形获得。所提出的光学系统简单，无需空间光调制器或机械相移装置。以带有蓝色发光二极管背光源的液晶显示器上显示的字母“A”作为物体的实验证实了所提出的获得非相干傅里叶全息图的方法。
