On the basis of the principles of structured light projection, phase shifting and triangulation, a new digital stereomicroscope system for micro-3D measurement is presented in this paper. Because the image fibre has many advantages such as direction changing and long distance transmitting without extra optics, this system also adopts it to project the structured light instead of the fixed optical systems. Thus, the measurement head is very small; the measurement distance and orientation could
