Science requirements and description of the 1 εm camera onboard the Akatsuki Venus Orbiter

This is the authors' abstract. We don't add key points for this paper.

The 1 εm camera onboard the Japanese Venus Mission/Akatsuki scheduled to arrive at Venus in 2015 or 2016 is described. In addition to its scientific goals, the optical and mechanical designs, the calibration procedures, and some results of feasibility studies are presented. Those studies are about the source of the contrast in the dayside image, the resolution of the H 2 O detection on the nightside surface, and a possibility of finding an active volcano.
