147 results about "Periscope" patented technology

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. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.

A radiation-resistant pan-tilt camera that can be replaced over long distances

ActiveCN116248988Bhigh image resolutionclear feedbackNuclear energy generationMechanical engineeringRadiation resistance
This invention discloses a remotely replaceable radiation-resistant pan-tilt camera, comprising: a fixed bracket with a wiring compartment fixedly mounted at its end; a pitch-rotation pan-tilt compartment mounted on the top surface of the wiring compartment; and a periscope lens compartment detachably mounted on the pitch-rotation pan-tilt compartment. The periscope lens compartment includes a fixing block, a fixing latch, a lens housing, and a lens module. Fixing latches are fixedly positioned at the center of both the left and right side walls of the lens housing. To improve the radiation resistance of the high-definition image sensor, this invention employs a three-layer shielding structure and a periscope reflective lens module to prevent direct damage to the camera sensor from radiation. The three-layer shielding structure also allows adjustment of the lens housing's center of gravity, ensuring the stability of the lens housing's pitch movement.
