Description
Technical Field
The invention belongs to the field of detection of quartz tubes and quartz rods, and particularly relates to a detector for detecting physical parameters including bubbles, impurities, bright spots, stress, refractive index distribution and the like of the quartz tubes and the quartz rods and a use method thereof.
Background
The high-quality quartz substrate tube is an indispensable raw material for preparing the optical fiber preform, and the defects of the substrate tube such as roundness, bow degree parameters, bright spots, bright lines, bubbles and the like directly determine the performance of preparing the optical fiber preform. At present, defects such as bright spots, bright lines and bubbles are tested by irradiating end surfaces through a strong light flashlight and then observing the conditions of the bright spots, the bright lines and the bubbles. Because the length of the quartz base tube is generally more than 1 meter, the method can also be used for observing the defect that the diameter is larger (generally a few tenths of a millimeter) and is close to a strong light flashlight, and once the defect is at the far end of strong light or tiny (in the order of 10 microns), the defect is unaddressed, and in addition, the test method is low in efficiency and easy to miss.
In addition, the deposited optical fiber preform also needs to detect parameters such as distribution of a deposited layer, DIP width, bow degree, roundness, bright spots, bright lines, bubbles, stress and the like. At present, PK equipment is adopted for measuring the distribution of the deposition layer, the DIP width and the roundness parameters, the equipment is high in price, the distribution of the deposition layer and the DIP width are all approximately fitted, and the real situation can not be reflected well in some cases. Parameters such as a bright spot, a bright line and bubbles of the preform are observed by irradiating the end face of the preform with strong light containing ultraviolet rays, and the conditions of the bright spot, the bright line and the bubbles are not detected by the fine (10-200 microns) defects, and the defects directly affect the performance of the subsequent optical fibers; secondly, the eyes of the measuring personnel are greatly damaged by ultraviolet rays.
