The Tine form of the Big Dam Changes to Monitor System

The high and precise laser in adoption spreads to feel machine, the application shield the system to compensate to make accuracy increased with the position several 100 the rice class of nm, can changes to monitor in the super and high the figure of dam its application. Not summit to degree of humidity, temperature, with the interference of the electromagnetism field. Can be in bad environment normal work. Test the precise X-Y of the terrace the work to the conduct and actions the set preceded the point designs, putting forward the project that error margin compensate. Make the principle error margin of the diagraph method as low as the degree of the micron class.
