The technology of linear CCD is widely used in untouched measurement system. There are requirement of making measurement system because the professional measurement device and laboratory equipment of linear CCD are very costly. Linear CCD chip is a core of the system. There are many linear CCD Driving designs, The former designs is hard to

Precise displacement measurement has an important role in industrial production. Displacement measurement based on the theory of grating moiréfringe has great significance due to its advantages such as high accuracy, low cost and so on. Grating moiréfringe signal is periodic signal, and it needs to be subdivided to obtain higher displacement resolution. At present there

It is estimated that the total production of axis part is at least 1 billion in China. About 70 percents of the part need to be measured and inspected. But at present the measuring technology in many factories is just taking use of mechanical measuring instrument or optic instrument with human vision. That may directly

In the automated assembly line of coiling system, the quality or standard of the final products would have been directly impacted by the unjustified edge of the roll folding material. The deviation would result in economic losses if we do not take measures in time. For example, in the production of steel strip, paper tape
