What is a periscope called, and how does a periscope work?

Hello, the principle of the periscope is to use two mirrors to make the object light reflected twice and fold into the eye. The reason why the periscope can see the top from below, and it is very clear, is that the two plane mirrors are parallel to each other, and both are at an angle of 45 degrees to the horizontal direction, and the scene is reflected and imaged twice by the plane mirror, so that the upper scene can be seen from the bottom. Periscope role:

The only way for a submarine to observe the situation at sea level and in the air is with the help of a periscope. Most submarines are equipped with two periscopes, one for attack and one for observation.

The principle of the periscope is that two plane mirrors are parallel to each other and at an angle of 45 degrees horizontally, and the imaging principle of the plane mirror is the reflection of light.

Working principle: According to the current technical level, the submarine comprehensive imaging system is basically composed of eight types of imaging systems. The following describes the technical status and characteristics of the eight imaging systems according to the order of the onboard and outboard imaging systems.

Periscope: refers to a device that protrudes from under the sea surface or from a low-lying pit to the ground to spy on the sea surface or activities on the ground. Its structure is the same as that of an ordinary terrestrial telescope, except that two mirrors are added to make the object light bent into the eye after two reflections.

Periscopes are often used in submarines, tunnels and tanks to observe the enemy.

The periscope has the same structure as a normal ground-based telescope, except that two additional mirrors are added so that the object light is reflected twice and enters the eye.

Summary. Hello, the periscope passes through the principle of reflection of a plane mirror.

It is to place two plane mirrors at the corners of the periscope at both ends respectively, the two mirror surfaces are flat and opposite, the angle is 45 degrees, and the light is propagated along a straight line and the angle of incidence of the plane mirror is equal to the exit angle, so that people can see things higher than the line of sight.

Hello, I'm Mr. Fang Tengfei Qin Qiaofu! I have seen your question, and now I am sorting out the answer, it will take 3 minutes, please forgive me for a while Thank you

I hope mine can help you before the liquid.,If you're satisfied, please give it a thumbs up.,Thank you for <> wild.

Periscopes are mostly used in submarines, tunnels and tanks, and periscopes are mainly used to observe enemy situations.

The only means by which a submarine in a state of underwater navigation observes the situation at sea level and in the air is with the help of a periscope. Most submarines are equipped with two periscopes, one for attack and one for observation. The former is used to find and target surface targets, while the latter is mainly used to observe sea and air conditions and navigational observations.

Periscope: refers to a device that protrudes from under the sea surface or from a low-lying pit to the ground to spy on the sea surface or activities on the ground. The periscope has the same structure as the telescope, but it needs to add two additional mirrors, and the pure finch judges that the object light is reflected twice and then folded into the eye. In addition, periscopes are often used in submarines, tunnels, and tanks to observe the enemy.

01 Reflection of light.

A periscope is a device that sticks out of the sea or from a low-lying pit to spy on the sea surface or activities on the ground. Its structure is the same as that of an ordinary above-ground telescope, except that two additional mirrors are added to make the object light reflected twice and folded into the eye. Periscopes are often used in submarines, tunnels and tanks to observe the enemy.

The main component of the periscope is a long steel tube mast that rises to a height of 5 meters outside the conning tower, with prisms and lenses installed at both ends and magnifying the periscope's field of view to 1x to 6x. There are two obvious problems with the use of periscopes. The main thing is the vibration problem.

When the periscope is fully raised, the slender periscope mast will affect the normal navigation of the submarine, causing lateral instability. When the submarine is moving at a speed of more than 6 knots, the periscope mast will cause a huge vibration that will cause a completely unusable situation. Later, additional mast mounts were installed on the submarine, and the shape of the top of the periscope was redesigned and improved to reduce water wave resistance.

Although the shock could not be completely eliminated, it was a big improvement. Another important issue is the fog produced by the periscope lenses. The air inside the submarine is humid, and the lenses of the periscope will produce fog, so the periscope must be designed and manufactured as waterproof and sealed as possible.

And submarines can easily damage the sealing structure of the periscope when they are attacked by deep bombs, which leads to the generation of fog.

The observation periscope has a seat and pedal that can cooperate with the movement of the periscope lifting lever, which is mainly used for sea and air observation and course confirmation before the submarine surfaces. The attack periscope does not have it, and it is mainly used for enemy observation, target ranging and attack angle calculation. At the same time, observation telescopes are also superior in their ability to observe at night.
