3It is the biography optical channel of connection quartz glass annulus and laser instrument, optical coupling element.Fibre bundle includes thousands of silica fibres, and every fibre diameter is 50-60mm.Effectively passing optical cross-section will cooperate fully with photo-coupler, to reduce the loss of light transmission.Photo-coupler plays the photoelectricity coupling, changes light signal into electric signal, and the decay in coupling time is as far as possible little.
The principle (see figure 3) of in medium, transmitting according to light, when light transmits by quartz glass annulus (BL), owing to the refractive index of air refraction less than quartz glass, luminous power will be limited in the quartz glass internal transmission, the decay of luminous power is very little, can ignore; When being attached with the salt dirt on the quartz glass annulus, because the refractive index of salt dirt is greater than the refractive index of quartz glass, some light can transmit from the dirty surface of the salt that adheres to, and promptly light is outwards revealed the loss that causes luminous energy herein, i.e. luminous power transmission is decayed.Along with increasing of salt dirt, the luminous power transmission attenuation is just big more.Therefore, the variation of the damping capacity by detecting the luminous power transmission promptly can be known and adhere to what of the dirty density of salt on the quartz glass annulus.
