Abstract: Wavefront aberration is the core index for high-precision optical systems, making its absolute detection essential. This paper introduces a combined error separation method based on rotation and its experimental technology that improves detection accuracy. According to the symmetrical distribution characteristic of wavefront aberration based on Zernike polynomials, rotate several specific angles respectively that corresponding result is obtained. Through multiple measurements, the detection accuracy of each specific angle position is improved. The main error sources are rotary table error and lens installation error which are analyzed by simulation based on physical optics and compensated by detection and calibration methods. Through experimental verification, the detection accuracy is significantly improved. The combined error separation method and related experimental technology have important application significance in wavefront aberration and optical surface shape detection.
