2
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
