A technique to alter the ratio of the horizontal and vertical resolution of a spatial light modulator has been proposed. This technique increases the horizontal resolution by a factor of K and decreases the vertical resolution by a factor of 1/K. The proposed technique increases the horizontal viewing angle by a factor of approximately K, although a conjugate image appeared. In the present study, the resolution redistribution technique is modified to eliminate the conjugate image. The height of a horizontal slit placed on the Fourier plane of a 4 f imaging system used for the resolution redistribution system is reduced by half. The horizontal resolution becomes K times larger, and the vertical resolution becomes 1/2K times smaller. The improved technique generates only the object wave. We demonstrated fourfold enlargement of the horizontal resolution to increase the horizontal viewing angle by approximately four times without generating the conjugate image.
已经提出了一种改变空间光调制器水平和垂直分辨率比例的技术。该技术将水平分辨率提高了K倍，同时将垂直分辨率降低了1/K倍。尽管出现了共轭图像，但所提出的技术将水平视角提高了约K倍。在本研究中，对分辨率重新分配技术进行了改进以消除共轭图像。用于分辨率重新分配系统的4f成像系统的傅里叶平面上放置的水平狭缝的高度减半。水平分辨率变为原来的K倍，垂直分辨率变为原来的1/2K倍。改进后的技术仅产生物波。我们展示了水平分辨率提高四倍，从而使水平视角增大了约四倍，且未产生共轭图像。
