Abstract

In this contribution, we present a study of the spatial resolution and quantitative phase imaging (QPI) performance of digital lensless holographic microscopy (DLHM) when holographic optical elements (HOEs) are employed as the illumination source of the system. The HOE employed in this study is a transmission hologram of a 3µm pinhole illumination system. We have quantified the imaging performance of the studied DLHM implementation by using a tailormade phase USAF test target. Results were then used to validate the dependence of the spatial resolution and phase sensitivity on the numerical aperture of the holographic point source.
