A universal smartphone add-on for portable spectroscopy and polarimetry: iSPEX 2

Spectropolarimetry is a powerful technique for remote sensing of the environment. It enables the retrieval of particle shape and size distributions in air and water to an extent that traditional spectroscopy cannot. SPEX is an instrument concept for …

Highly-multiplexed Bragg gratings for optically adding spectral lines

The Hera Saturn entry probe mission

The Hera Saturn entry probe mission is proposed as an M-class mission led by ESA with a contribution from NASA. It consists of one atmospheric probe to be sent into the atmosphere of Saturn, and a Carrier-Relay spacecraft. In this concept, the Hera …

Use of neural networks in ground-based aerosol retrievals from multi-angle spectropolarimetric observations

In this paper, the use of a neural network algorithm for the retrieval of the aerosol properties from ground-based spectropolarimetric measurements is discussed. The neural network is able to retrieve the aerosol properties with an accuracy that is …
