Laser displacement sensor capable of adaptively adjusting installation distance

The invention relates to a laser displacement data acquisition and light path adjustment device, in particular to a laser displacement sensor. The laser displacement sensor comprises a laser displacement meter, a light path adjustment device-reflecting mirror. By the device, the problem that the displacement meter must be placed within a distance deformation surface special range to effectively acquire displacement when the laser displacement meter is used in a test site is solved. The device is simple to operate, the test accuracy of the laser displacement meter is not affected, debugging andinstallation operation before test is greatly reduced, and the laser displacement sensor can be used for most of test sites requiring displacement measurement. 本发明专利涉及种激光位移数据采集与光路调节装置，尤其是种激光位移传感器。由激光位移计，光路调节装置-反射镜组构成。该装置解决了在测试现场使用激光位移计时，必须将位移计放置在距离变形表面特定范围才能有效采集位移的问题。该装置操作简单，不影响激光位移计的测试精度，大大减轻的测试前的调试和安装工作，可用于大多数需要进行位移测量的试验场所。
