Precision can be defined as the closeness in agreement of results during a series of repeat measurements under presumed identical conditions. These results are often expressed as a standard deviation.

Many people use the words “accuracy,” “precision,” and “resolution” as if they were synonyms, even though they are all very different. For example, datasheets for products as diverse as test & ...

Laser interferometry has emerged as a pivotal technique for precision measurement, utilising the interference of coherent laser beams to detect minute displacements and variations in optical path ...
