ODS instrument of ExoMars-2022 project: Structure, main characteristics and results of laboratory calibrations

Résumé

The paper presents the ODS (Optical Depth Sensor) instrument developed at the Institute of S of the Russian Academy of Sciences for the ExoMars-2022 project. Designed for long-term op surface of Mars, ODS shall provide daily measurements of optical thickness of dust and conde in the planet's atmosphere from the illumination of its surface. To participate in the ExoMars-20 ODS instrument was upgraded and underwent a full cycle of ground testing. The paper instrument design, its optical scheme and the spectral characteristics of two optical channels. considers the parameters of the temperature sensor incorporated in the instrument. The resul calibrations of the device parameters such as field of view, spectral characteristics and calibrat temperature sensor are given. In the experiment it is found that the instrument has spectral tr the range of 350-450 and 740-1030 nm, the field of view of the instrument is from 18 to 33° 45° in zenith angle. The instrument has been tested in the temperature range -40 to +40 °C.
