Why LUC-POINT™
Precision at Distance
Long range and high precision usually exclude each other. Laser triangulation loses precision with the square of distance. Interferometers are very precise, but their range is short and they react to vibration and air flow. Contact probes are stable, but they cannot reach far targets, and they wear.
LUC-POINT™ uses FMCW coherent ranging. It compares the frequency of the return with the local oscillator, not the return intensity. The sweep linearity and bandwidth of the laser set the precision, so precision does not degrade quickly with distance. Coherent detection also rejects ambient light.
Comparison with Common Methods
| Principle | Characteristics | |
|---|---|---|
| LUC-POINT™ | FMCW coherent ranging | High precision at long range, no contact |
| Laser interferometer | Interference counting | Higher precision, but short range and sensitive to the environment |
| Contact probe | Mechanical contact | Stable, but needs contact and wears |
| Laser triangulation | Geometric triangulation | Simple, but precision drops quickly with distance |
