Definitions
- a beam of light emitted by a light source is divided into a measurement light and a reference light by a beam splitter, and is directed to the reference plane and the target plane respectively, and the reflected two beams overlap and interfere with each other at the beam splitter.
- the target plane moves, the light and dark fringes of the interference pattern will change the corresponding number of times and the number of changes will be recorded by the photoelectric counter. From this, the distance of the target plane can be calculated, but the measurement range is limited by the wavelength of the light wave, which is not suitable for measuring unevenness. Complex surfaces with large changes.
- a layer/element when referred to as being "on" another layer/element, the layer/element may be directly on the other layer/element, or there may be an intermediate layer/element between them. element.
- the layer/element may be located "under” the other layer/element when the orientation is reversed.
