Abstract: In order to enhance the five-axis turn-table angle location measure precision in hardware-in-the-loop simulation,a dual-frequency laser phase measure system is designed.Build a dual-frequency laser phase measure path with a multi-tooth dividing table and do a test on the five-axis turn-table,the measurement error is analyzed.The results show that the multi-tooth dividing table can be used for big angle range location.In every ±5°range,the measure error can be less than 0.5″. It can be used for the high precision angle location measurement for five-axis turn-table in HWIL simulation lab.
