Infrared optical fiber spectroscopic sensor for rust detection of elevator steel wire ropes

This paper presents an infrared optical fiber spectrum sensor for detecting the rust of elevator wire rope. The sensor is composed of incident infrared fiber, receiving infrared fiber, fiber collimator, fiber angle regulator, condenser, fiber coupler, thread rod and fiber fixer. One end of the incident infrared fiber is connected with the fiber coupler, and the other end is connected with the fiber collimator. One end of the receiving infrared fiber is connected to a fiber coupler, and the other end is coupled to a condenser. The condenser is used to collect the beam of light emitted by the incident fiber and reflect the beam of light through the wire rope, and transmit the focused beam to the receiving infrared fiber. The horizontal angle of the incident infrared optical fiber collimator is adjusted by the optical fiber angle regulator, and the distance between the infrared incident optical fiber collimator and the infrared receiving optical fiber condenser is adjusted by the threaded rod. The incident infrared fiber, receiving infrared fiber, optical fiber collimator, optical fiber angle regulator, condenser, optical fiber coupler and threaded rod are fixed by the optical fiber fixer to form a whole, which is the sensor used for the rust detection of the elevator rope.
