In this paper, the imaging features of an incoherent holographic structure is analysed more thoroughly. The relation between the lateral resolution and frequency sampling step in an incoherent holographic system which is indeed a multi-view projection structure is formulated mathematically. Based on the presented mathematical relation the image resolution is improved through synthetically enlarging the lenses aperture. The non-uniform frequency sampling due to enlarging the lenses aperture is resolved through time-multiplexing. Through the proposed dual-mode, spatio-temporal, incoherent holographic structure, image quality and resolution is improved considerably. Experiments are performed to validate the claimed quality improvement.

横向分辨率提高的双模非相干 3D 成像系统

本文更深入地分析了非相干全息结构的成像特征。在实际上是多视图投影结构的非相干全息系统中,横向分辨率和频率采样步长之间的关系是用数学公式表达的。基于所提出的数学关系,通过综合扩大镜头光圈来提高图像分辨率。通过时分复用解决了由于扩大镜头孔径而导致的非均匀频率采样。通过提出的双模、时空、非相干全息结构,图像质量和分辨率得到显着提高。进行实验以验证声称的质量改进。
