AI Technical Summary

Technical Problem

The prior art cannot conduct full-cycle real-time detection of laser products under vibration conditions, resulting in distortion of the test results and cannot reflect the laser status in actual applications.

Method used

A laser characteristic detection device for vibration test is designed, including a vibration table, a support frame and a power detection mechanism. The laser under test is fixed on the vibration table. The power detection mechanism is used for real-time detection through the lens barrel, a focus lens and a power meter. The probe is coaxial with the lens barrel to ensure detection accuracy.

Benefits of technology

Real-time detection of laser products under vibration conditions is achieved throughout the whole cycle, ensuring the reliability and authenticity of the test results, and can accurately determine whether the laser is irradiated normally, and reflect the performance of the laser under test in vibration conditions.

Abstract

The invention relates to the technical field, and discloses a laser characteristic detection device and method for a vibration test, the detection device comprises a vibration table, a support frame and a power detection mechanism, a tested laser can be fixed on the vibration table, the support frame is arranged on one side of the vibration table, and the power detection mechanism comprises a lens cone, a focusing lens and a power meter. The lens barrel is adjustably connected to the supporting frame in the X direction, the Y direction and the Z direction and located above the vibration table, the focusing lens is installed in the lens barrel and right faces the vibration table, the power meter comprises a probe and a displayer which are electrically connected, the probe is connected to the end, away from the vibration table, of the lens barrel, and the position of the probe relative to the lens barrel is adjustable in the X direction and the Y direction. The detection method is based on the detection device. The technical problem that in the prior art, full-period real-time detection of a laser product under a vibration test cannot be achieved is solved, and the detection result is reliable and real.
