Periscope Diagram Submarine. To accomplish this it is necessary that the periscope be long enough to extend beyond the surface and that means be provided to deflect the horizontal rays of light first in a downward direction and then horizontally to the eye of the observer. The essential function of a periscope is to give an officer conning a submarine a view of the surrounding horizon while his vessel remains submerged.
To accomplish this it is necessary that the periscope be long enough to extend beyond the surface and that means be provided to deflect the horizontal rays of light first in a downward direction and then horizontally to the eye of the observer. The submarine periscope type ii is a general purpose instrument of 40 foot nominal length and 7 1 2 inch outer diameter. In its simplest form it consists of an outer case with mirrors at each end set parallel to each other at a 45 angle.
A periscope is an instrument for observation over around or through an object obstacle or condition that prevents direct line of sight observation from an observer s current position.
The essential function of a periscope is to give an officer conning a submarine a view of the surrounding horizon while his vessel remains submerged. The periscope is used in the submarines to see the events that are happening behind a wall or a barrier and some submarines use complex periscopes that use the prisms or advanced fiber optics instead of mirrors to provide them the magnification complex periscopes operate on submarines and in different fields of science.
