3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Angular movement angularmovement
αx, αy
The laser beam in the XZ and YZ plane angle amount to move.
Note. The amount of the optical axis of the coordinate system X, Y, Z are defined. If the angle X and Y directions to move the ratio of no greater than 1.15, the beam angle is considered
To move rotationally symmetrical, in which case only the angular movement characterize, symbols denoted α with a value.
3.2
Beam pointing stability beamangularstability
δαx, δαy
Beam angle to move 2 times the standard deviation.
Note. The amount of the optical axis of the coordinate system X, Y, Z are defined. If the Y-direction than the pointing stability of the X direction is not greater than 1.15 is considered beam
Pointing stability is rotationally symmetrical, in which case only one value is the beam pointing stability, symbolically written as δα.
3.3
Origin pivot
The intersection of all the instantaneous axis and Z axis.
NOTE. In many cases, the origin is not necessarily exist, so the origin of this measure is not a standard content.
