Sticking your head out to look; a simple mirror on a stick; a periscope-type device; a fibreoptic camera and screen.
A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.
The basic periscope uses flat mirrors, to bend and offset the optical path. If magnification is required, then the periscope will use convex objective and eyepiece lenses, becoming a refracting telescope with an offset in its optical path.
In a tube, the light will bounce off on a 45 degree mirror twice until it will reach your sight.

The periscope has several parts: the ocular lenses, the mirror or prism, inversion/reversion prisms, relay lenses, another mirror or prism, and objective lenses.

Tape a mirror to the inside of each flap. cut away the side of the cardboard opposite each flap. Angle both mirror flaps inward about 30 degrees. Look through the bottom of the periscope to see that what is seen on the top mirror is also reflected on the bottom mirror.

Because there are two mirrors: one at the bottom and one at the top. If there was only one mirror in it, it would be, but because the image is inverted in one mirror, then that image is inverted again in the second mirror, it goes back to normal and you see the normal image which is entering the periscope at the other end.
Helicopters do not have any mirror on top of the rotor. Periscope mirror is equipped on some aircraft to have clear vision of runway to pilot.
it is prism
