ROTARY UNIT FOR NON-CONTACT SENSOR

摘要

A measuring instrument for making linear scans of an object is including a linear scanning laser sensor (2), a supporting unit (3) for positioning the sensor (2) and an adapter for connecting a sensor joint portion (2a) to a distal end portion of the supporting unit (3). The supporting unit (3) includes a rotating biaxial joint (3d) for alignment of the distal end portion. The adapter is a rotary unit (1) with a first member engaged with the distal end portion and a second member engaged with the sensor joint portion (2a) wherein the first and the second members are rotatable relative to one another by an angle of 90°. In case of interferences in a first direction, the direction of the linear scanning laser sensor (2) can be changed to allow accurate three- dimensional measurements.
