Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.

In the precision test of the factory, the detection of large-size samples is often encountered. The conventional method is to segment the detection on the universal tool microscope or projector. It is not economical or disadvantageous to process the sample plate to assist the measurement reference surface. Improve inspection accuracy and post-repair re-inspection when making samples. Let's take a large-scale model of our factory as an example to introduce a detection method that is simple, practical and accurate.
