This paper proposes the measurement method for the surface profile of aero-engine blades based on multi-line laser sensing, which demonstrates excellent applicability for the 3D surface measurement.

Many laser measuring tools also provide area or volume measurements, as well as an impressive accuracy range that can measure to within ⅛, 1/16, or even 1/32 inch. After testing many of the top ...

This 3D-printed confocal laser scanning microscope is a good example of an instrument for measuring really small stuff. As [Zachary Tong] points out, confocal scanning microscopy uses a clever ...

Since early demonstrations of femtosecond laser as a three-dimensional (3D) processing tool ... or quantum-bit devices, require higher manufacturing spatial resolution (less than 10 nm, far ...

Continuous operation is much faster but also less accurate. The result is a 3D point cloud in which each point stands for a laser pulse or distance measurement. There is also a camera system with up ...

Metrology Parts has announced the release of its latest resource "A Comprehensive Guide to 3D Metrology." This resource covers 3D metrology by providing information on the history and evolution of ...
