Paper Abstract

In this paper, it is described the work principle and total structure and design of the laser-scanned measuring systerm for the large diameter. Signal characteristics of scanning system is described,the circuit and method for boundaries detection and drift errors. The feasibility of the system is tested by practice, the accuracy of boundary distinguishing is up to ±1μm,and continuous working errors up to ±5μm,measurement range up to 0~400mm. This system shows a better method for measuring large diameters.
