• Resumen

  • Lensless object scanning holography (LOSH) has been recently proposed as a fully lensless method, capable of improving image quality in reflective digital Fourier holography, and involving an extremely simplified experimental setup. LOSH is based on the recording and post-processing of a set of digital lensless holograms which finally yields in a synthetic image with improved resolution, field of view (FOV), signal-to-noise ratio (SNR), and depth of field (DOF). LOSH validation has been previously validated for one-dimensional (1D) objects and now it is expanded to twodimensional (2D) ones. Experimental results are presented showing an impressive image quality improvement
