查询词典 perpendiculars

On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.
