The electrical signals are real-time processed by a computer and the measurement results are displayedthrough a digital display in the end. In the paper, firstly the working principle of laser scanning caliper gauge was discussed, then an intact system of a laser-scanned diameter gaugewas designedand the basic factors which influences the accuracy and stability of the system is discussed and the solving methods were put forward. This system has characteristics of detection speed, high precision, non-conta...
