摘要：

A large-scale laser plane calibration system is developed. This plane is constructed by a 35 m long horizontal granite guide rail and a 1.5 m long vertical metal guide rail. Two dual-frequency interferometers are used to measure the coordinates of a target moving on the plane. One of them can measure the horizontal displacement while eliminating the Abbe errors caused by the straightness of the granite guide rail. Another measures the sum of horizontal displacement and vertical displacement. This laser plane can be used as a lab standard to calibrate portable coordinate measuring machines by measuring the target on the plane. Calibration tests for a laser tracker are given.
