Everyone should be familiar with frogs. They can eat pests in crops for people, which is a good thing for farmers. helper. But do you know? Frogs can only see things that move. If an object stays still, it cannot see it.
To this end, the scientist also conducted an experiment. The scientist captured several frogs, and also prepared some bugs and a rope. The scientist placed the bugs in front of the frogs, and the bugs stopped motionless in front of the frogs. , but the frog didn't eat it for a long time, so he tied the bug with a rope and let it float in the air. This time, the frog swallowed the bug in one bite. The scientist tested several frogs and came to the same conclusion. The frog could only We see moving bodies but not static bodies.
Based on the visual principle of frog eyes, scientists have developed an electronic frog eye. This electronic frog eye can accurately identify objects with specific characteristics just like real frog eyes. After installing electronic frog eyes into the radar system, the radar's anti-interference ability is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles to prevent fakes from being confused with real ones. Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the takeoff and landing of aircraft, and if it detects that the aircraft is about to collide, it can issue an alarm in time. In traffic arteries, it can direct the movement of vehicles and prevent vehicle collisions.
Scientists get inspiration from natural creatures and make inventions and creations. Biology is truly mankind’s best teacher!
