MIRIS (Multi-purpose Infrared Imaging System) is the main payload of the STSAT-3 (Science and Technology Satellite 3) and composed of two cameras, the SOC (Space Observation Camera) and the EOC (Earth Observation Camera).
The SOC is the first Korean infrared space camera for the space observations.
To acquire the best quality of infrared imaging, we have to cool the detector down to 90 K and the telescope to 200 K for the reduction of thermal noise. To achieve these goals we finetuned the thermal design of structure, based on which the flight model is manufactured and assembled. The flight model was successfully launched and is performing the missions. The telescope of SOC is the refractive optical system with five lenses, out of which the rear surface of fifth lens is aspheric. This design guarantees the optimistic performance to the wide field of view, ∼3.6°×3.6°. In the front of the optical telescope, the Winston cone baffle is attached to evade possible stray light from the Earth. The telescope is manufactured in the room temperature, but designed to perform the best performance at the temperature of 200 K which can be achieved through passive cooling on the orbit. We used various materials for lenses for the best performance in the near-infrared wavelengths. Each lens were coated to reduce the reflectance and to improve the transmittance. We confirmed that the SOC is cooled down as expected and is now performing the mission observations.
The EOC is an infrared camera to certificate the successful space operation of domestic infrared sensor and to monitor the Korean peninsula during national emergency. Its observation wavelength is from 3 to 5 μm with a single filter. The sensor of EOC is also cooled down by a small cooler, but the optical system and structures are remained at the environmental temperature. The EOC is also successfully operating and we confirmed that it can resolve the structures on Earth, e.g., rivers, larger than about 100 m.
