3 Principles and Applications of EDM
The principle of optical interference is presently used in interferometers for metrology, for high precision distance measurements over short distances and for the definition of the metre.
Optical Power Meter
An optical power meter is defined as an instrument used to measure power or energy from narrow band sources, such as lasers, without a dispersing element and with broad band sensitivity. It
