The noise-limited resolution is defined as the signal amplitude (rms) at which the signal-to-noise ratio is 0 dB with 1 Hz
spectral resolution, measured in a distance of 0.5 m on 3M Scotchlite™ Tape (retro-reflective film).
Frequency-dependent

The attainable resolution is frequency-dependent and is specified for frequencies above 10 Hz. In the frequency range from
10 Hz to 5 kHz the specified decoder noise is superimposed by the scanner noise. The resolution is then between 0.1 and

The maximum amplitude of the distortions refers to the full scale.An exception of this is just a peak in the frequency range
20…25 kHz and its multiples. This peak is generated by the laser in the optical sensor, the amplitudes depend on the stand-off
distance. The CoherenceOptimizer can cause interferences at a frequency of 610 Hz and harmonics.
