Paper Abstract

We designed, realized, and tested a pocket module that allows performing off-axis Digital Holography microscopy with no need for an interferometer setup. A commercial plastic chip is engineered for the scope. Our strategy is moving complexity from the reconstruction algorithms and the external imaging apparatus to the chip itself, using custom optical components. We functionalized the chip with a photoresist grating and polymer lenses, to avoid the need for a reference arm as well as external optical components. Thanks to the single beam scheme, the system is robust against vibrations and the stability of fringe patterns implies enhanced portability.
