The camera will observe Jupiter and its satellites providing detailed maps of their surfaces and atmospheres. During the mission, the camera will face a huge variety of observing scenarios ranging from the imaging of the surfaces of the satellites under varying illumination conditions to limb observation of the atmospheres. The stray-light performance of JANUS has been studied through non-sequential ray-tracing simulations with the aim to characterize and optimize the design. The simulations include scattering effects produced by micro-roughness and particulate contamination of the optical surfaces, the diffusion from mechanical surfaces and ghost reflections from refractive elements. The results have been used to derive the expected stray-light performance of the instrument and to validate the instrument design. | Conference Name: | Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28182 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10698/106984V/Modeling-the-JANUS-stray-light-behavior/10.1117/12.2313204.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510619494 9781510619500 |
