| description | The invention relates to a displacement deformation measuring device and method based on a PSD and laser ranging. A laser emitting end and a laser receiving end are included; the laser emitting end isprovided with a laser range finder, a semiconductor laser and a control box; the laser receiving end is provided with a PSD position sensor mounted on a measured object; the laser range finder, the semiconductor laser and the PSD position sensor are all connected into a data transmission interface of the control box through cables; two channels of laser beams of the laser range finder and the semiconductor laser are irradiated on the PSD position sensor to form two spots; and when the measured object has displacement changes, lateral position change data are measured by the PSD position sensor, and longitudinal position change data are measured through the laser range finder. By means of the displacement deformation measuring device and method, long-time, real-time and uninterrupted continuous monitoring can be a |
