Resumo

Microscopes are essential imaging tools for accessing micro scale information in several contexts, including routine visual analysis for cell culture. As an alternative to traditional optical microscopic instrumentation, lens-free microscopy is an emerging modality, which is efficient to provide portable apparatus that provides images with decoupling resolution from the field of view. This paper presents compact and easy-to-use imaging equipment based on optical lens-free holographic microscopy, which performs amplitude and phase images from a sequence of captured images at different distances from the sample, resulting in images with almost 30 square millimeters and 4 micrometers of resolution.
