Through the optical model, the multi-DOF motion can be carried out by the laser spot variation. The multi-DOF measurement system includes 2 digital image sensors and 4 laser diodes. It improves the disadvantage of conventional multi-DOF measurement system. The conventional multi-DOF measurement system usually needs many position sensing detectors (PSD) and each PSD must have enough space. Therefore, the conventional multi-DOF measurement system needs large space. Because one image sensor can sense multi laser spot simultaneously, the structure of proposed multi-DOF measurement system can be simplified. ? 2013 IEEE.Digital image sensorsImaging sensorsLarge spacesMeasurement systemMulti degree-of-freedomOptical modelingOptical system modelingPosition sensing detectorsImage sensorsInstrumentsOptical systemsMeasurementsconference paper10.1109/I2MTC.2013.65554812-s2.0-84882273403
