Light attenuation detection device

Technical Field

The utility model relates to the technical field of optical fiber detection, in particular to a light attenuation detection device.

Background

Optical fibers are short for optical fibers, and are fibers made of glass or plastic that can be used as a light conducting means. The principle of transmission is 'total reflection of light'. The front hong kong university of chinese ministry high roll and George a. hockham first proposed the concept that optical fibers could be used for communications transmission, the high roll thus enjoying the 2009 nobel physics prize, with the tiny optical fiber encased in a plastic jacket so that it can be bent without breaking. Typically, a transmitter at one end of the fiber uses a light emitting diode or a beam of laser light to transmit a pulse of light to the fiber, and a receiver at the other end of the fiber uses a light sensitive element to detect the pulse. In daily life, optical fibers are used for long distance information transmission because the loss of light transmitted through optical fibers is much lower than the loss of electricity transmitted through electric wires. In general, the terms optical fiber and optical cable are to be confused. Most optical fibers must be covered by several layers of protective structures before use, and the covered cables are referred to as fiber optic cables. The protective layer and the insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from damaging the optical fiber, such as water, fire, electric shock and the like. The optical cable is divided into: optical fiber, buffer layer and coating. Optical fibers are similar to coaxial cables except that the mesh shielding is not present. The center is the glass core through which the light propagates. In the multimode optical fiber, the core diameter is 50 μm and 62.5 μm, which are approximately equivalent to the thickness of human hair. And the diameter of the single-mode optical fiber core is 8-10 μm. The core is surrounded by a glass envelope having a lower refractive index than the core to keep the light rays within the core. Further on the outside is a thin plastic outer sleeve to protect the envelope. The optical fibers are typically bundled and protected by an outer jacket. The core is usually a double-walled concentric cylinder of small cross-sectional area made of silica glass, which is brittle and easily broken, and therefore requires the addition of a protective layer. Traditional optical fiber detection instrument uses optic fibre to insert detecting instrument's optic fibre dish inboard, but it exists to connect unstablely, and it can't guarantee subsequent measured data's accuracy, causes the condition of the damage of bending to the optic fibre easily when measuring simultaneously, consequently, provides an optical attenuation detection device to above-mentioned problem.
