What is the measuring principle of optoNCDT ILR2250? |
|||
Light in the visible wavelength range is modulated with suitably chosen frequencies such that the exact distance can be derived from the multiple of the relevant modulation wavelength contained in the distance to be measured and from the size of the remaining interval. The remaining interval is measured using analogue phase comparison methods. Several modulation waves are used to determine the distance. |

SMR - Start of measuring range, minimum distance between sensor and target EMR - End of measuring range (start of measuring range + measuring range), maximum distance between sensor and target MR - Measuring range |
