We recently introduced a polariscopy method which can determine feature orientation below the diffraction limit. Measuring transmission at four linear polarisations (0,45,90,135°), information about the orientation of absorbers or patterns and features inside an object could be determined. This is applicable to transmitted/absorbed and scattered/reflected light as well, across the EM-spectrum. We investigate the feasibility of applying this technique to remote sensing satellites. Altimeters are able to determine many oceanographic parameters based on the surface height mapping (e.g., current directions, tidal waves etc). The nature of this measurement means the range and azimuth lateral reso..View full abstract
We would like to thank Bertrand Chapron and Alexey Mironov from Ifremer for guiding us towards satellites with polarisation components, introducing us to the data, and numerical modelling discussions. Takuji Waseda from The University of Tokyo for discussions on sea ice monitoring. Blake Allan from Deakin University for his advice on their drone's capabilities and for being the pilot for the eventual drone flight. We are grateful for the startup funding of Swinburne's Nanotechnology facility and its continued support.
