The periscope was invented in the year 1854 by French inventor Hippolyte Marié-Davy.
The periscope was invented in 1450 by Johann Gutenberg.
In a periscope, light enters through one end of the periscope and undergoes refraction at the first mirror, which changes the direction of light. The light then reflects off another mirror and exits the other end of the periscope. This allows the viewer to see objects that are not in a direct line of sight.
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.

A periscope typically contains two mirrors - one at each end of a hollow tube. The first mirror at the top of the periscope reflects the image into the tube, and the second mirror at the bottom of the periscope reflects the image out to the viewer's eye.
