Embodiment Construction
[0025] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.
[0026] Such as figure 1 As shown, a data acquisition method, including
[0027] 1. Optical power data collection:
[0028] Fix the optical fiber assembly 1, and move the laser 2 relative to the optical fiber assembly 1 after powering on, so that the light emitted by the laser 2 passes through the ceramic ferrule 11 of the optical fiber assembly 1, and the optical signal received by the optical fiber assembly 1 is converted into optical power by the photoelectric converter 3 The analog signal is converted into an optical power digital signal by the analog-to-digital converter 6;
[0029] 2. Location data collection:
[0030] While collecting the optical power data, use the position feedbac...

The invention relates to the technical field of data acquisition, and in particular relates to a data acquisition method and device thereof. The data acquisition method comprises the following steps: (1) optical power data acquisition; (2) position data acquisition; and (3) synchronization of the position data and the optical power data. The data acquisition device comprises an optical power data acquisition module, a position data acquisition module, and a processor for performing real-time one-to-one correspondence on the optical power data and the position data acquisition. The position data and the optical power data are synchronized at a high speed, so that the position information and the optical power information are in one-to-one correspondence, and high-speed scanning by use of the movement of a laser device is realized. A position feedback element feeds back the data of the real position of the laser device, so that the optical power data and the position data are in real one-to-one correspondence, the offset of each of the acquired position and optical power is greatly reduced, and the synchronization error of the position information and the optical power information is minimized.
Description
technical field [0001] The invention relates to the technical field of data collection, in particular to a data collection method and a device thereof. Background technique [0002] The axial laser includes an optical fiber assembly and a laser welded and packaged with the optical fiber assembly, and the optical fiber assembly is provided with a ceramic ferrule. When welding and packaging optical fiber components and lasers, it is necessary to ensure that the focal point of the laser after the laser is energized is located in the center hole of the ceramic ferrule to obtain the best conduction rate, thereby obtaining the maximum optical power and reducing the defect rate of the product . [0003] The traditional way to obtain the maximum optical power is to use manual testing. Manual testing has a large workload, slow speed, low efficiency, and poor accuracy, which often leads to defective products and cannot meet the needs of production. It is urgent to provide a solution....
