Because you can achieve time (day), all (no gaps) in a real-time situation awareness and information acquisition, this technology in astronomy meteorology, environmental monitoring, frontier, aerospace and other fields, can a thirst.
Human activities, the required information of 90% from Visual, but its gaze angle only forward-46 °, representing 4% of the angular airspace, blind area accounted for 96%.
And near-surface fish field angle of up to 180 °, the eye no rotation, even without head or body, the "Omni-aware" a certain distance of scene information, effective response from above the water surface in any direction.In the last 20 years, as an important branch of bionics, "infrared fish eye study" research in the emerging international, domestic research and international advanced level.
China ordnance Engineering College Professor Wang Chung-and his team "Bionic mini infrared imaging detection system BMIRIDS" beginning in 1998, 2003 China invention patent, than the United States and Europe for 2 years in advance.Near the surface of the fish in the bottom sky, above the surface of the water cannot be perceived threats, hemispheric airspace that first benefited from the lens in the eye and the water environment.
From optical structure, Fisheye, convex surface of the front and around the water to form a water as the medium layer of "water lens", relative to the horizontal plane (curvature is 0), fish eyes surface curvature is large, so the "water lens" is a negative light power (absolute value) of great Plano-concave lenses.Because you can achieve time (day), all (no gaps) in a real-time situation awareness and information acquisition, this technology in astronomy meteorology, environmental monitoring, frontier, aerospace and other fields, can a thirst.
Wang Chung-Professor says, "infrared FishEye" monitoring is not dead, and even can be monitored against the wall action of "Spiderman", can become Bank and community security work.
