Experimental design shows submicron resolution imaging in three-dimensional objects using digital holographic microscopy, suggesting new imaging capabilities.
I designed and experimentally performed digital holographic microscopy (DHM) in which a halogen lamp is used as a light source and theoretical two-point resolution is submicron. The DHM system consists of a commercially available optical microscope and a common-path self-reference in-line digital holography system. Quantitative phase imaging of a three-dimensional (3D) object is performed without speckle noise. 3D imaging of an object containing submicron apertures is performed with temporally incoherent thermal light.
