Abstract

The invention discloses a laser used vibration measurement device and its adjustment method wherein the device comprises a first laser, a second laser, a third laser, a first reflection mechanism and a second reflection mechanism. The first reflection mechanism is mounted at the emitting light path of the first laser; and the first reflection mechanism is used to change the light path of the light from the first laser. The second reflection mechanism is mounted at the emitting light path of the second laser; and the second reflection mechanism is used to change the light path of the light from the second laser. The emitting light from the first reflection mechanism and the second reflection mechanism converges with the emitting light from the third laser. The first reflection mechanism and the second reflection mechanism both consist of an optical lens assembly and a driving mechanism wherein the driving mechanism is used to drive the optical lenses in the optical lens assembly to move to change the direction of the emitting light. According to the invention, it is possible to change the working distance of a laser used vibration measurement device simply and effectively. In addition, the size and weight of the laser used vibration measurement device can be reduced; the cost can be too. Therefore, the manufacturing of such device become easier.

Description

Technical field [0001] The invention relates to the field of laser measurement, and in particular, to a laser vibration measurement equipment and an adjustment method thereof. Background technique [0002] Vibration widely exists in various fields such as life, industrial production, and scientific research. In these fields, there is a great demand for vibration measurement. The measurement of vibration is divided into contact measurement and non-contact measurement. Among them, non-contact measurement will not affect the original state of vibration, and the measurement results are more accurate and reliable, and it has become the development direction of vibration measurement. [0003] At present, the more mature non-contact vibration measurement technology is laser Doppler technology, which generally adopts a heterodyne structure. Laser vibration measurement has many advantages such as non-contact, high accuracy, and easy installation. It has been widely used in material flaw ...
