The basic principle and characteristics of laser triangulation range imaging system based on a synchronized scanners are presented. The general trajectory circle equation is derived theoretically. The maximum and minimum ranges of the system detection are obtained. The system performances, such as the lateral measurement scope, the depth of field, the resolution and so on, are given, which are relative to the system parameters. After analyzing the effect of system parameters on the resolution and the measurement scope of the system, some suggestions for design considerations are put forward.
