THz detection thickness | Laser thickness measurement | Spectral confocal thickness measurement | |
---|---|---|---|
Affected by environment | Unaffected by light and temperature | susceptible to temperature effects | susceptible to temperature effects |
Ranging range | Compatible with long-distance/near distance measurement | Narrow range of distance/thickness measurement | Only supports single point measurement |
Effect of flatness | The effect of surface roughness is negligible | Surface roughness has a greater impact on accuracy | Surface roughness has a greater impact on accuracy |
line scan | support | not support | not support |
Electrical characteristic detection | support | not support | not support |
