A periscope is very simple to construct. It is simply a small, long box with rectangular holes cut into the top and bottom at opposite sides. Mirrors are set behind these openings at 45 degree angles so that the image viewed at the top is reflected by the first mirror to the second and then to the observer. Periscopes fitted on submarines use this same basic setup, adding a series of lenses to magnify the image over a longer distance.
