Abstract
We develop new sonar system by way of acoustic focusing which is totally different from conventional one in principle. It focuses input wave on the opposite edge of the lens without aberration perfectly. Then, the motion of acoustic source is read by naked eyes. It can be used as an acoustic window deep underwater by converting sound into light. We introduce the sonar in actual size that can be used underwater and report current situation of the development.
