Improving fringe projection 3D shape measurement

Based on a novel measurement algorithm and the Mikrotron EoSens 12CXP+ area scan camera, scientists in Taiwan developed a system to reconstruct a 3D model in a continuous scan mode instead of the conventional approach of taking three full-field fringe images sequentially in pause mode.

CMOS vs. CCD technologies

CMOS is becoming increasingly popular, but CCD is far from obsolete. When does which image sensor technology make sense and where do both play out their advantages? So far, CCD sensors still impress with higher image quality and lower noise, whereas CMOS sensors score in terms of energy consumption and smear and blooming effects. With more choice of global shutter sensors, CMOS continues to catch up.

100% inline thickness measurement of strip and sheet materials

The thicknessGauge systems provide highly accurate thickness values for strip and plate materials. In addition to the C-frame models, they can also be integrated into the production line as an O-frame version. By using various sensor technologies such as laser scanners, laser triangulation sensors, confocal sensors and electromagnetic combination sensors, they can be adapted to the measurement task and the object surfaces to be measured.
