According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion.
Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.
People have successfully designed an accurate "jellyfish ear" instrument by simulating the organs of jellyfish that feel infrasound waves. It consists of a loudspeaker, a vibrator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. This instrument can forecast storms 15 hours in advance.
The compound eyes on both sides have the greatest influence on the behavior of horseshoe crab. After being irradiated by the light beam, the compound eye produces a pulse. One eye is irradiated by the light beam, and the other eye generates the main pulse; Both eyes are irradiated by light beam at the same time, and both eyes generate pulses at the same time, but the frequency of pulses generated by light beam irradiation on one eye is slightly lower. Inspired by it, mankind has successfully developed an electronic simulation device, which can solve the network equation composed of 10 elements. The TV camera made by applying this principle can provide high-definition TV images under laser.
Without nature, there would be no beautiful earth. Let's join hands to protect nature and the earth.
