The high- and medium-resolution integrated stereo camera (HiMeRISC) is a two-component system consisting of a high-resolution camera (HRC) and a medium-resolution stereo camera (MRSC) designed for stereo mapping of the Martian surface and high-spatial-resolution imaging of selected regions. An off-axis three-mirror system is used in the HRC, with a focal length of 5000 mm, a field-of-view of 2° and an F-number of 12.5. Over 10-km-wide areas can be imaged in a resolution of 0.5 m pix-1 (at 300-km orbit altitude by the HRC). The MRSC has a focal length of 32 mm, a field-of-view of 66°, an F-number of 6.8 and a working wavelength range of 450–750 nm. Areas with widths of 250 km can be imaged in a resolution of 50 m pix-1 (at 300-km orbit altitude). MRSC was aligned, and the test results showed good image quality. HiMe-RISC can provide various imaging modes with the combination of the two cameras, and it will be particularly useful in the geological research in Mars-exploring experiments.
