Paper Abstract

A method of digital holography for high-resolution microscopy at long working distance is proposed using a synthetic aperture. A series of digital holograms covered different spatial frequency ranges of an object optical field are recorded by using different tilted object illuminations. Subsequently, the intensity images are numerically reconstructed and magnified respectively. Finally, a synthetic image with the resolution improved and speckle noise suppressed is obtained by synthesizing these reconstructed images. The results show that the proposed method can be easily used to in-situ microscope at a long working distance.
