“…And based on the test results, the turntable is calibrated and error compensated.The autocollimator calibration turntable experiment is shown in Fig 4. The 23-sided prism combined with the photoelectric autocollimator was used to carry out several sets of experiments on the turntable to test the rotation angle accuracy of the turntable, and based on the test results, a corresponding error compensation model was established [7] .Experiments were carried out according to the experimental steps, and multiple sets of experimental data were obtained. The average error value is shown in Table 1.…”

This paper presents a turntable system, which can be used for torque, angle calibration. Based on the design of the turntable,the calibration experiment of the turntable system is carried out by using photoelectric autocollimator, and an error harmonic compensation model was established to compensate the angle measurement error of the turntable. The angle measurement accuracy of the designed turntable system is improved.

“…In this paper, the inner and outer of the dual-axis turntable are used to realize the high-precision continuous angle measurement with the autocollimator as the angle reference, and the closed-loop compensation of the drift of the autocollimator is realized by using the combination of the compensation target and the fixed target [9][10].…”

In order to solve the problems such as the limited field of view of traditional self-collimation detection, the inability to achieve continuous detection of 0~360° full circumference and the existence of zero drift in self-collimation measurement. The positive and negative rotation of the inner and outer axes of the dual-axis turntable is used to realize high-precision continuous angle measurement with the autocollimator as the angle reference, and the combination of the compensation target and the fixed target is used to realize the closed-loop compensation of the drift of the autocollimator. The results show that: the repeatability error of the system is 0.05”, and the detection accuracy of the system reaches 1.64”. On the premise of ensuring the stability of the self-collimation angle reference, the self-collimation full-scale small angle measurement is realized.
