Early examples Johann Gutenberg, better known for his contribution to printing technology, marketed a periscope in the 1430s to enable pilgrims to see over the heads of the crowd at the vigintennial religious festival at Aachen. Simon Lake used periscopes in his submarines in 1902
The first periscope was invented in the early 19th century by a French engineer named Marie Davey. He used it as a way to see over obstacles while remaining hidden.
well there really is no antonym that i know of for periscope because a periscope is an object.
The captain of the submarine raised the periscope to see if there's danger.
Periscopes A periscope is a instrument of observation used for naval use or for other war-like purposes. In fact the first periscope prototype was made by Johann Gutenberg which was used to enable people to see over the heads of the crowd at the Vigintennial religious festival at Aachen. In the navy it is used in submarines to view possible threats such as enemy submarines or sea mines. Marie Davey built the first naval periscope, a simple, fixed periscope using mirrors in 1854. A periscope works by using two mirrors to bounce light from one place to another. A typical periscope uses two mirrors at 45 degree angles to the direction one desires to see. The light bounces from one to the other and then out to the person's eye.
In paintball wars, a periscope is a handy way to look around a corner without getting shot. With only its periscope out of the water, a submarine was nearly impossible to spot at a distance.

You tell me
The captain of the submarine raised the periscope to see if there's danger.
In trench warfare much use was made of devices which allowed an observer to safely see across no-mans land. The periscope was one such item.The periscope was made of wood and folded into halves so as to allow ease of carriage. When used in the trenches the folding periscope was often camouflaged with sacking. A periscope is also used for looking out of boats to see if an enemy ship is around.
