Abstract
We demonstrate a high resolution lens-free holographic microscopy in reflection geometry based on a pixel super resolution (SR) method. The lens-free microscopy uses a novel Michelson geometry suitable to image reflective samples with the large field of view, while the Fourier domain SR technique is applied to obtain the high resolution hologram, achieving the sub-pixel resolution of 1.2 μm in the USAF reflection target by utilizing the randomly shifted low resolution images. The proposed compact microscopy technique enables to provide high resolution amplitude and phase imaging, those are suitable for biology and semiconductor imaging applications.
