Measuring night sky brightness: methods and challenges
Andreas Hänel, Thomas Posch, Salvador J. Ribas +10
Measuring the brightness of the night sky has become an increasingly important topic in recent years, as artificial lights and their scattering by the Earths atmosphere continue sp…
Second-order coherence properties of amplified spontaneous emission from a high-power tapered superluminescent diode
Jan Kiethe, Axel Heuer, Andreas Jechow
We study the degree of second-order coherence of the emission of a high-power multi-quantum well superluminescent diode with a lateral tapered amplifier section with and without fe…
Imaging and mapping the impact of clouds on skyglow with all-sky photometry
Andreas Jechow, Zoltán Kolláth, Salvador J. Ribas +3
Artificial skyglow is constantly growing on a global scale, with potential ecological consequences ranging up to affecting biodiversity. To understand these consequences, worldwide…
Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept
Andreas Jechow, Zoltán Kolláth, Amit Lerner +4
Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefor…
