Abstract :
We demonstrate a numerical aperture improvement of ~3 fold using pixel-super-resolution in lensfree on-chip microscopy. This improvement was confirmed using both a CCD and a CMOS imager chip, empirically pointing to the same space-bandwidth improvement factor, leading to giga-pixel range reconstructed lensfree holographic images.
