Embodiment approach

[0092] Such as figure 1 As shown, according to an embodiment of the present invention, the focusing subunit 21 includes: a rear lens 211 , a first mirror 212 , a first beam splitter 213 , a front lens group 214 , and a first wave plate 215 . In this embodiment, the rear lens 211 , the first reflection mirror 212 , the first beam splitter 213 , the front lens group 214 , and the first wave plate 215 are sequentially arranged to form the first optical path. In this embodiment, the second optical path is connected with the first optical path through the third beam splitter 114 and the rear lens 211 . The measurement light transmitted by the third beam splitter 114 is delivered to the rear lens 211, the measurement light is focused by the rear lens 211, and the focused measurement light is delivered to the first reflector 212, and reflected by the first reflector 212, The measurement light is focused to the first focal point B, and after entering the first focal point B, the meas...

Abstract

The invention relates to a laser vibration measurement system which comprises a laser unit (1), a focus imaging unit (2), a focusing unit (3) and a control unit (4), wherein the focus imaging unit (2)is connected with the laser unit (1); the focusing unit (3) is connected with the focus imaging unit (2), wherein the control unit (4) is connected with the focus imaging unit (2) and the focusing unit (3). The laser vibration measurement system provided by the invention can automatically complete the identification and the vibration measurement of an object, so that the manual operation processis reduced. Meanwhile, as laser is adopted for the vibration measurement, manual focusing, identification and other processes are not required in the whole process, so that the injury to an operator is avoided, and the safety of the whole measurement system is improved. The measurement system provided by the invention realizes the coaxial synchronization of laser focusing and image acquisition during the laser vibration measurement, so that the measurement accuracy and the measurement efficiency of the whole measurement system are improved.

Description

technical field [0001] The invention relates to a vibration measurement system, in particular to a laser vibration measurement system. Background technique [0002] With the continuous upgrading and development of industry and technology, the application of vibration measurement is becoming more and more extensive, and the requirements for laser vibrometers are also showing a trend of diversification. Among them, the automation and intelligence of laser vibrometer equipment has become an important development. direction. This requires that the laser vibration measurement equipment should be able to automatically focus and also have the target recognition function, which is convenient for the tester to remotely control or automatically control the laser vibration measurement equipment through a robot to lock the target of interest and extract its vibration information. [0003] The current common method is to install an image acquisition device parallel to the optical axis o...
