Measuring system and method for large-scale plane pointing change

Abstract

The invention discloses a measurement system for large-scale plane pointing changes, which includes a linear laser transmitter, a one-dimensional PSD measurement point, a measurement controller and an information processor; the information processor is connected with the measurement controller for data, and the The measurement controller is connected with the linear laser emitter control, and the one-dimensional PSD measuring point is multiple, wherein each one-dimensional PSD measuring point is provided with a one-dimensional PSD sensor, and the light output by the linear laser emitter It is transmitted to a one-dimensional PSD sensor, and the one-dimensional PSD sensor is connected to the measurement controller for data; a plurality of the one-dimensional PSD measuring points are arranged on a large plane. At the same time, the measurement method of the above measurement system is provided. The measurement method of the present invention is to obtain the position change of each measuring point through the linear laser combined with the one-dimensional PSD sensing technology, and obtain the pointing change of the large-scale plane by solving, so as to further adjust or compensate the large-scale plane.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a measurement system and method for large-scale plane pointing changes. Background technique [0002] In the field of measurement technology, measurement applications of large-scale planes are usually involved. For example, the orientation of large-scale planes changes due to deformation or vibration. It is necessary to measure the orientation changes of large-scale planes. [0003] Existing measurement methods usually have the following defects: [0004] 1. Automatic measurement cannot be realized; [0005] 2. The volume and weight of the measuring equipment are large; [0006] 3. Strict requirements for the layout of measuring equipment; [0007] Not suitable for measuring pointing changes on large flat surfaces. Contents of the invention [0008] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a measurement system and meth...
