Addition of digital holography enables the use of feedback by measuring the quantitative phase of specimen near real time and in situ nondestructively. After each near UV exposure, phase retardation map of exposed photopolymer is measured with digital holography part of the system. Any deviation from target phase is corrected by changing the pattern displayed on the mask.https://biocil.github.io/tr/publication/2022_spiepe_gurcan_a/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2022_spiepe_gurcan_a/A label free quantitative phase imaging method is realized in this project to enable imaging of an interface between different media. This system is based on an off-axis holographic microscope and uses a high numerical aperture (NA) microscope objective to achieve total internal reflection (TIR).https://biocil.github.io/tr/funding/120f099/Tue, 15 Sep 2020 00:00:00 +0000https://biocil.github.io/tr/funding/120f099/
