Issue Date: | 2018 | Volume: | 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace) | Series: | IEEE METROLOGY FOR AEROSPACE | First Page: | 252 | Abstract: | We report about the measurement of the Noise- Equivalent Spectral Radiance (NESR) of the VIHI imaging spectromter aboard ESA's Bepi Colombo mission to Mercury. The knowledge of the NESR allows to determine the capability of an optical detector to measure faint signals. A description of the setup used to determine the NESR during the prelaunch calibration campaign is given. The processing of the data col- lected at various operative temperatures and integration times is described. The sensitivity study of the NESR has been performed at the expected detector's temperatures and integration times with the goal to determine the minimum spectral radiance at which VIHI is sensitive during the different observation phases of the mission. A simulation of the expected Signal-to-Noise Ratio (SNR) of VIHI during the different orbital phases is provided. | Conference Name: | 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace) | Conference Place: | Roma | Conference Date: | 20-22 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28606 | URL: | https://ieeexplore.ieee.org/document/8453616 | ISSN: | 2575-7482 | ISBN: | 978-1-5386-2474-6 | DOI: | 10.1109/MetroAeroSpace.2018.8453616 | Bibcode ADS: | 2018maes.conf..252F | Fulltext: | open |
