We present a new lensless incoherent holographic system operating in a synthetic aperture mode. Spatial resolution exceeding the Rayleigh limit of the system is obtained by tiling digitally several Fresnel holographic elements into a complete Fresnel hologram of the observed object. Each element is acquired by the limited-aperture system from different point of view. This method is demonstrated experimentally by combining three holographic elements recorded with white light illumination which is emitted from a binary grating.
我们展示了一种在合成孔径模式下运行的新型无透镜非相干全息系统。通过将多个菲涅耳全息元件数字拼接成被观测物体的完整菲涅耳全息图，获得了超过系统瑞利极限的空间分辨率。每个元件由有限孔径系统从不同视角获取。通过组合用从二元光栅发出的白光照明记录的三个全息元件，对该方法进行了实验验证。
