Description
Summary:In this paper, we use multipoint light source illumination to enhance the resolution of digital holographic microscopy. The specimen is sequentially illuminated from many directions by using multipoint light sources which are created by a lens-array. The high spatial frequency information of the specimen is directed to the limited numerical aperture of the objective lens and captured at a fixed position of image sensor. The three-dimensional information of the specimen can be reconstructed with enhanced resolution by reconstructing the captured holograms.
