1.2
Important terms
Phase measurement
Distance measuring procedure, which determines the distance of an object by the
shift of the phase angle of the light reflected from the object.
Uniqueness range
Due to the periodicity of the sinusoid, the phasing of the signals received by the
ODSL 30 limits the determination of unique measurement values to within a specific
interval. The length of this interval is called the uniqueness range. A large uniqueness
range is equivalent to high background suppression (see chapter 3.8.2).
Absolute measurement accuracy
Shows the possible divergence of the measurement value from the anticipated value
through changes in the environmental conditions during the measuring process.
Higher accuracy is given at constant environmental conditions.
Repeatability
Measuring distance change with repeated measurement at the same output signal
(observe the same peripheral conditions as with resolution).
Resolution
The smallest possible distance change of the measurement object, which causes a
definite change in the output signal.
