periscope

An optical instrument designed to displace the line of sight in a vertical direction. For submarines and other military uses the periscope is a long tube containing prisms at both ends and intervening imaging and relaying lenses. Several anatomical inspection devices such as cystoscopes, laryngoscopes and otoscopes use similar optical systems, though on a minuscule scale.
