Abstract
The planeness measurement of solar panel substrate is a key problem in the manufacture procedure of satellites. The current measuring methods have the problems such as low precision and low efficiency. Based on the actual engineering project of the solar panel substrate planeness measuring system, a solar panel substrate planeness non-contact measuring system is presented, which employs an optical triangulation method and bases on virtual precise datum plane. By means of a declinate optical triangulation measuring instrument structure which is firstly proposed, the measured area and resolution of this measuring system are greatly increased, and the high accuracy non-contact measurement of the planeness of a large area plane is realized. On the basis of a new modeling method of virtual precise datum plane and measurement error compensation technique, the measuring system can accurately measure the solar panel substrate planeness on a non-precision plate. The actual measurement results show that the measurement accuracy 0.02mm (RMS) can be obtained when a solar panel substrate (2581mmx1755mm) planeness is measured by using of this measuring system.
