Stray-light suppression with high-collection efficiency in laser light-scattering experiments
Applied Optics, 1992We describe an optical system that we constructed to collect a large fraction of fluorescent light emitted isotropically from a cylindrical interaction region. While maintaining an overall detection efficiency of 9%, the system rejects, by more than 12 orders of magnitude, incident laser light along a single axis that intersects the interaction region.

Stray light suppression baffle with radial leaves
17th Congress of the International Commission for Optics: Optics for Science and New Technology, 1996In this paper, we propose a new type of optical baffle with radial leaves, which can effectively reject stray light caused by primary mirror scatter while makes the baffle length shorter than the ordinary one. The stray light test setup for measuring the Point Source Transmittance (PST) of such an optical baffle is described. The test results show that

Methods to suppress stray light in black materials
SPIE Proceedings, 2004We have investigated several methods to reduce reflectance and scattering levels from a selected group of highly absorbing materials. Each material has vastly different morphologies but similar reflectance and scattering levels. The highly absorbing materials considered in this study include: fibrous black appliques, carbon aerogels, Martin Black, and ...

Stray light suppression in InGaAs/GaAsSb type-II FPA
SPIE Proceedings, 2016Stray light in focal plane array (FPA) deteriorates the accuracy of hyper spectral imaging. Multiple reflections between FPA window and peripheral region of a sensor chip are considered to be the major sources of stray light. One idea for suppressing the stray light is to shield the incident light on the peripheral region of the sensor chip by ...

Stray light suppression of optical and mechanical system for telescope detection
SPIE Proceedings, 2013During telescope detection, there is atmosphere overflow and other stray light affecting the system which leads to background disturbance. Thus reduce the detection capability of the system. So it is very necessary to design mechanical structure to suppress the stray light for the telescope detection system.

Measurement of Aureole and Suppression of Internal Stray Light of Aureole Photometer
Chinese Astronomy and Astrophysics, 2011Abstract A modern aureole photometer (AP) was developed for the site survey inWest China, in preparation for the installation of future large solar equipments. The performance of this new AP was tested in preliminary observations, and a lot of sky brightness data were accumulated at a few sites in Yunnan Province.

Grating scatter is an important performance index for plane grating, and its measurement is a difficult problem for grating research field. In order to achieve stray-light of the instrument itself to be less than 10(-8) so that the grating scatter can be accurately measured, stray light in diffraction grating monochromators has been studied and an opto-

Stray Light Characterization and Suppression in Laboratory Testing of Coronagraphs
Research in Astronomy and AstrophysicsAbstract Stray light suppression is a key challenge in the development of high-performance coronagraphs. Laboratory measurements, however, are often affected by environmental interferences such as collimator-induced stray light, indoor reflections, and dust scattering.

Optimal design of a gravitational wave telescope system for the suppression of stray light
Applied OpticsFor gravitational wave detection, the telescope is required to have an ultra-low wavefront error and ultra-high signal-to-noise ratio, where the power of the stray light should be controlled on the order of less than 10 −10 .
