Development of a high-speed CMOS drum camera with multiple focal depths

We experimentally made the high-speed drum camera which had the motor of 80,000 rounds per minute (rpm) at rotating mirror on object beam. This paper describes results of the experiments about its basic optics, the subjects in the future and plans for improvement of the performance. The experimental monochromatic CCD image showed that the optical system employed in present study is proper basically. Additionally, this camera enable to the high-speed photography at about 520,000 frames per second, and we could show the specific policy to realize 1,000,000 frames per second in the near future.
