Insight from Darkness: Nanophotonics for real-time phase imaging
Grant number: DP160100983 | Funding period: 2016 - 2019
This project aims to develop ultrathin surfaces patterned on the nanoscale for extracting information from optical wavefields. These devices can be designed to provide real-time phase contrast imaging of transparent objects. This capability would open up the possibility of live-cell imaging with no expensive optical components and no, or minimal, computational post-processing. The planar configuration is designed to be compatible with next-generation lab-on-a-chip technologies and permit rapid throughput diagnostics with potential applications in biomedicine and materials science. Expected project outcomes may also underpin fundamental advances in understanding the interaction of light with ..View full description
