A Fast Star-Detection Algorithm under Stray-Light Interference
Photonics, 2023 The interference caused by stray light leads to the invalid attitude of star sensors in orbit, thus affecting the attitude control of satellites. In order to overcome this problem, this paper proposes a fast star-detection algorithm with strong stray ...

Stray light suppression in spectroscopy using periodic shadowing [PDF]
Optics Express, 2014 It is well known that spectroscopic measurements suffer from an interference known as stray light, causing spectral distortion that reduces measurement accuracy. In severe situations, stray light may even obscure the existence of spectral lines. Here a novel general method is presented, named Periodic Shadowing, that enables effective stray light ...

Fiber-based stray light suppression in spectroscopy using periodic shadowing [PDF]
Optics Express, 2021 Stray light is a known strong interference in spectroscopic measurements. Photons from high-intensity signals that are scattered inside the spectrometer, or photons that enter the detector through unintended ways, will be added to the spectrum as an interference signal.

A model for suppressing stray light in astronomical images based on deep learning. [PDF]
Sci RepAbstract Wide-Field Small Aperture Telescopes (WFSAT) are widely used for surveilling space objects. Due to their wide-field of view (FOV) characteristics, these telescopes can cover a large areas of the sky at once, improving observation efficiency.

Mechanical Integration of a Prism-Grating-Prism-Assembly for the CO2M Mission [PDF]
EPJ Web of Conferences, 2022 We developed and realized a mechanical integration concept of a prism-grating-prism-assembly for the CO2M mission. The mechanical design of the mounts relies on a kinematic mounting of the optical elements.

Stray-light Suppression for the MIRACLS Proof-of-principle Experiment [PDF]
Acta Physica Polonica B, 2020 The Multi-Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS), currently under development at ISOLDE/CERN, aims to combine the high resolution of fluorescence-based collinear laser spectroscopy (CLS) with a high sensitivity. This will be achieved by confining 30-keV ion bunches in a Multi-Reflection Time-of-Flight (MR-ToF) device which ...
