The Environmental Light Characteristics of Forest Under Different Logging Regimes. [PDF]

Ecol Evol
The environmental light field system excels at measuring fundamental attributes of the whole scene natural light regime in different forest types. ABSTRACT Light is a fundamental attribute and key abiotic driver in forest ecosystems. Although the ecological effects of light itself is well studied, capturing the complex parameters that constitute the ...

Research on polarization effect suppression method of weak starlight simulation device

Optics Express
Under the influence of the polarization effect, the background stray light of the weak starlight simulator and the polarization state of the simulated target star point are doped with each other, so it is difficult to achieve accurate suppression of polarized stray light.

Evidence for cloud-to-cloud variations in the ratio of polarized thermal dust emission to starlight polarization

Astronomy & Astrophysics
The correlation between optical starlight polarization and polarized thermal dust emission can be used to infer intrinsic dust properties. This correlation is quantified by the ratio RP/p, which has been measured by the Planck Collaboration to be 5.42 ...

Dust polarization from starlight data [PDF]

AIP Conference Proceedings, 2002
We present a statistical analysis of the interstellar medium (ISM) polarization from the largest compilation available of starlight data, which comprises ~ 5500 stars. The measured correlation between the mean polarization degree and extinction indicates that ISM dust grains are not fully aligned with the uniform component of the large-scale Galactic ...

A Bio-Inspired Navigation Strategy Fused Polarized Skylight and Starlight for Unmanned Aerial Vehicles

IEEE Access, 2020
The migratory animals are capable of traveling long distances by fusing varied information, such as the halteres, the star positions, and the polarization pattern.

Interstellar Polarization Survey. II. General Interstellar Medium

The Astronomical Journal, 2023
Magnetic fields permeate the entire Galaxy and are essential to, for example, the regulation of several stages of the star formation process and cosmic-ray transportation.

The EUV Reflectance of Mercury's Surface Measured by BepiColombo/PHEBUS

Journal of Geophysical Research: Planets, Volume 128, Issue 3, March 2023., 2023
Abstract On 9 and 10 October 2021, Probing the Hermean Exosphere by Ultraviolet Spectroscopy aboard BepiColombo observed the disk‐integrated reflected light from the Sun by Mercury in the spectral range 90–160 nm at a phase angle of 70°. These observations are used to derive the EUV reflectance of the surface of Mercury in this wavelength range for the
