| Abstract: | The paper presents a measurement mathod of the position errors of the zoomset and the compensating set in a continuous zoom telescope with two double-frequencylaser interferometers and the cause of effecting measuring accuracy is analyzed. This noncontact method has the advantages of high measuring accuracy, convenient adjustmentand less introduction error |
