For physicists, measuring the precise magnitude of a physical quantity is a key to understanding quantum mechanics. However, there is a limit to how precise a measurement can be made, which is ...

The atomic clock comes in many varieties. Some are chip-sized electronics, developed for the military but available commercially now, while bigger and more accurate atomic clocks keep track of time on ...

Three-dimensional (3D) surface geometry provides essential information in various sciences and precision engineering. Fringe Projection Profilometry (FPP) is one of the most powerful non-contact (thus ...

High precision and large measurement range are the target of any one three-dimensional scanner. For a line structure light vision sensor, measurement precision depends on its calibration results, i.e.

Measurement of auricle parameters for planning and post-operative evaluation presents substantial challenges due to the complex 3D structure of the human auricle. Traditional measurement methods rely ...

New laser distance meter features a 670ft measuring range, 8× digital camera zoom, a sunlight-readable AMOLED touchscreen, and ±1mm accuracy.
