What did the compound eyes of flies invent for humans?

People according to flies.

The structure of the compound eye is modeled after the "fly's eye" camera.

Scientists have discovered through the study of the eyes of flies:

The fly's eyes are very special, there are 5 of them. Three of the smaller ones are monocular, which is perceived to be bright, and the other two are compound eyes, each consisting of many hexagonal visual units. These many eyelets are self-contained, with separate optical systems and nerves to the brain, and the optic nerves of these eyes can work together in harmony and independently.

Therefore, the fly's eye not only has the ability to distinguish speed and height, but also can perceive the vision from different directions, which is why it is easy to be spotted when people use a fly swatter to hit it from behind. This compound eye has a high temporal resolution, and it divides moving objects into successive single shots, with each eye taking turns to be "on duty".

The special structure and function of the fly's eye inspired scientists to develop the fly's eye lens, mounted it on the camera, and made the "fly's eye camera, whose lens is made of 1329 small lenses glued, this peculiar "fly's eye camera" has a high resolution, with a resolution of up to 400 lines per centimeter, this camera can be used to replicate the microscopic circuitry of the computer, and it can shoot dozens, hundreds or even more than a thousand photos of the same or different at a time**, There are also special uses in scientific research and in the military.

1.Gas Testing Instruments.

Flies have a very sensitive sense of smell, and people have imitated this characteristic of flies to measure trace amounts and other gases to be measured.

2.Fly's Eye" camera.

A gray fly is on the table, if you catch it with your hand, then it is always your hand that has not yet fallen, it has already flown away from this "place of right and wrong". What is the reason for this?

The study of the eyes of flies has revealed that the eyes of flies are made up of many hexagonal visual units, i.e., small eyes. This compound eye has a high temporal resolution, it can divide a close object into a continuous single lens, and each small eye takes turns to "be on duty", and people imitate the "fly's eye" camera according to the structure of the fly's compound eye.

3.Vibrating gyroscope.

The hindwings of the fly degenerate into a pair of balance rods. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the direction of movement of the wings, which is to keep the fly's body flat.

Scale's navigator. Based on this principle, scientists have developed a new generation of navigators - vibrating gyroscopes.

Humans used flies to invent the fly's eye camera, the "fly's eye" aerial camera.

1. Fly's eye camera.

The body is similar to that of a regular digital camera, but the internal structure is very different. Typically, a camera captures light with a main lens and then focuses on a film or photoreceptor behind the lens. The sum of all the rays forms a small dot on the ** to display the image.

The special camera is placed between the main lens and the photoreceptor, and there is a microscope array filled with 90,000 microlenses. Each small lens array receives light from the main lens neck and transmits it to a photosensor, where the focused light is separated and the optical data is converted and recorded digitally.

2. "Fly's Eye" aerial camera.

The Americans invented the "fly's eye" aerial camera based on the principle of the compound eye of a fly, which can take more than 1,000 high-resolution shots at a time**. Astronomy also has an optical instrument called the "fly's eye", which can detect the light of a shower on a moonless night. According to the structural characteristics of the compound eye of flies, the multi-mirror optical system of the instrument was designed.

Extended: The fly's eye is also a natural speedometer that can measure its own flight speed at any time, so as to track the target in fast flight. Based on this principle, an electronic instrument called the "Aircraft Ground Speed Indicator" was developed to measure the speed of the aircraft relative to the ground and has been used in aircraft.

The structure of this kind of instrument gripper is simple, that is, two photoelectric receivers at a certain angle to each other (or one photoelectric receiver at the nose and one at the tail) are installed on the fuselage to receive the optical signal at the same point on the ground in turn. According to the time difference between the signals received by the two receivers, the flight altitude at that time is measured, and then calculated by the computer, and the flight speed of the aircraft relative to the ground is displayed on the instrument.

The cornea of a fly is used to create a biomimetic surface or a surface that mimics the properties of biological tissues. These surfaces can be used in a variety of applications, including solar cells.

Hello, flies invented the "fly's eye lens", which is made up of hundreds or thousands of small lenses neatly arranged in a stupid omenous column, and can be made into a "fly's eye camera" by renting it as a lens, which can take thousands of identical photos at a time. This type of camera has been used in printing plate making and in a large number of tiny circuits of electronic computers, which greatly improves ergonomics and quality. The "fly's eye lens" is a new type of optical component, and it has many uses.
