Title: Analysis of measurement accuracy′s influence on measurement turn-table axial nonorthogonality
Abstract: Discussing measurement parameter error that is caused by the measurement turn-table cross shaft and vertical axis nonorthogonality during opto-electric measurement angular device is tested.Presenting a new method on error.Deducing error equation that used vector rotating and transfer of axes theory,Measuring out measurement parameter error on different orthogonality by testing optical-electrical device.The experimental result is that position angle maximal error is-5″;pitch angle maximal error is-13.2″,when nonorthogonality isβ≤5′,Accord with accuracy standard.
