We demonstrate theoretically and experimentally a method to break the Rayleigh limit of an imaging system by modulating only the aperture of the imaging optics. By fully utilizing the useful information extracted from an image sequence, a superresolution image with high-frequency components beyond the cutoff frequency of the imaging system is reconstructed. Resolution enhancement of 2 times is achieved experimentally. Simulation results show that the method can still work with the signal-to-noise ratio of ~ 10 for the acquired images.

通过光圈调制突破瑞利极限

我们在理论上和实验上演示了一种仅通过调制成像光学器件的孔径来突破成像系统瑞利极限的方法。通过充分利用从图像序列中提取的有用信息，可以重建具有超出成像系统截止频率的高频分量的超分辨率图像。实验中将分辨率提高了2倍。仿真结果表明，该方法仍可在采集图像的信噪比约为10的情况下工作。
