Abstract

The invention discloses laser vibration measurement equipment and an adjusting method thereof. The equipment comprises a first laser device, a second laser device, a third laser device and a focusing device. The focusing device comprises a plurality of lenses. Light emitted by the third laser device is transmitted along optical axes of the multiple lenses. A first light path changing device is arranged on the light emitting light path of the first laser device. A second light path changing device is arranged on the light emitting light path of the second laser device. Light emitted by the first light path changing device and the second light path changing device is parallel to light emitted by the third laser device. The focusing device is used for performing focusing on parallel light from the first and second light path changing devices and the third laser device. The distance between the light emitting light path of the third laser device and each light emitting light path in the first and second light path changing devices is a first distance. The minimum distance between the light emitting light path of the third laser and the light emitting positions of the first laser device and the second laser device is a second distance. The first distance is smaller than the second distance.

Description

technical field [0001] The invention relates to the field of laser measurement, and in particular, relates to a laser vibration measurement device 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 the measurement of vibrations. Vibration measurement 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, which has become the development direction of vibration measurement. [0003] At present, the relatively 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 precision, and easy installation. It has been widely use...
