Comprehensive institute develops Japanese industry technology to press 100femto(femto=10 recently - 15 square) second interval launchs laser measure machine, with the distance that this will come to measure the object that be measured, when can assuring to measuring limits to be tens of rice to be measured to the length of 1km, its error is 2 μ M only. In the past, when undertaking Sunday run is measured, rise very hard measure resolution, want to produce the error of several millimeter commonly. New-style measure machine use double shade to undertake comparative, because this suffers temperature and baric effect scarcely, undertake compensating very convenient also. What this technology can use at industrial robot is visual part, what have precision work to the curved surface of large paraboloid antenna or serve as corrective range finder is fiducial implement.
