Embadometry

from Wikipedia, the free encyclopedia

The Embadometrie (( Greek ) Embadon visible surface and μέτρον (métron) level ) is concerned with the quantitative measurement of surfaces. The term comes from the astrologer of Queen Elizabeth John Dee (1527-1608) in his book " The Mathematicall Praeface to Elements of Geometry of Euclid of Megara ".

Measurement method

The special measuring method of embadometry is usually an optical measuring method for the quantitative measurement of a surface. The difference between this and other known measuring methods lies in the quantitative approach, which, unlike other measuring systems, does not measure a surface as precisely as possible , but rather averages a defined area. Where optical methods with measuring points in the nanometer range scan and measure a surface in a linear manner, embadometric measurement is carried out with a beam geometry in the millimeter to centimeter range. This enables extensive scanning, the measurement result of which represents the surface quantitatively in measured values.

Application in surface recognition

It is conceivable to use this quantitative measurement signal to detect a surface measured in advance, since the measurement for this special area will provide a constant result.

Application in quality inspection

The shape deviation of a surface, which is significant to the rest of the structure, stands out from the averaging of the quantitative measurement and is therefore suitable for use in quality assurance in the area of ​​fault location.
