BLUE: Brillouin - backscatter - fluorescence LIDAR research for Underwater Exploration of marine litter

Plastic marine litter is a very complex global environmental issue, with plastic litter at the sea surface representing only a small fraction of plastic entering the sea. In this respect, the BLUE project investigated the potential of diverse LIDAR techniques (backscatter, fluorescence, Raman) to address the detection of plastic litter not only floating on the sea surface, but also suspended in the first few metres under the surface, with also a focus on detecting microplastics and discriminating plastic from other types of litter. The approach adopted was four-fold:

Ge on Si Feasibility

The focus of study is to build near-IR capability onto Si CCDs for Time-Delay-Integration (TDI) applications, with the main requirement being charge domain summation, which allows the lowest noise performance on these types of devices. Currently there is no product that exists to do this. Si CCDs are a well-established technology which, whilst being an “old” technology, are still world leading in certain applications up to a wavelength of ~1μm.

Light Absorption Enhancement with Bio-inspired Nanostructures

Light-trapping helps enhance the light absorption in space solar cells and hence enables their thickness to be reduced to increase the radiation hardness. We have optimised light-trapping structures (LTS) inspired in the diatom frustule and moth’s eyes. As a solar cell reference, we use the commercial 3G30C model from Azure Space Solar Power GmbH. We have developed a physical model to describe the solar cell absorption and derive the efficiency. The optical description relies on the Fourier modal method and the solar cell performance on the detailed balance limit.

RESMALI: Remote Sensing for Marine Litter

According to the United Nation Environment Program (2005), “Marine Litter” is defined as any item that has been made or used by people and deliberately or accidently discarded either directly into the sea or coast or transported from land into the marine environment.
