This book introduces various kinds of high-precision measurements, including the measurements of time and space, digital activity, border sensors and other physical quantities. Further, it demonstrates how to eliminate the quantitative errors believed to be the main problem in measurements using the border effect.

This book introduces various kinds of high-precision measurements, including the measurements of time and space, digital activity, border sensors and other physical quantities. Further, it demonstrates how to eliminate the quantitative errors believed to be the main problem in measurements using the border effect. In metrology technology, detection resolution is crucial to improving measurement precision in devices and instruments, and since the resolution is limited, a fuzzy area is usually found during detection. As such the book presents numerous experimental findings showing that the measurement precision can be improved by two or three orders of magnitude compared to traditional methods by achieving stability of resolution and more accurately detecting the border of the fuzzy area.
