SOlar Diameter Imager and Surface Mapper (SODISM)

The Solar Diameter Imager and Surface Mapper (SODISM) is an 11-cm diameter telescope on board the PICARD space mission. It measures the solar irradiation and provides wide-field images of the photosphere and chromosphere of the Sun in five narrow pass bands (centered at 215.0, 393.37, 535.7, 607.1, and 782.2 nm).太阳直径成像仪与表面测绘仪（SODISM）是搭载于PICARD航天任务平台上的11厘米口径望远镜。该仪器测量太阳辐射，并能在五个窄带通光范围内（中心波长分别为215.0、393.37、535.7、607.1和782.2纳米）提供太阳光球层和色球层的宽场图像。
