Abstract. The actual problem of modern metrological maintenance in optical technologies related to highprecision control of the radius of curvature and shape parameters of optical mirrors is discussed. A comparative analysis of technical characteristics of modern interference systems and optical-electronic devices based on wavefront sensors such as Shack — Hartmann (SHWFS) is presented. An original circuit solution for development of a modernized functional diagram of the interference control equipment based on wavefront sensor (OEDWFS) for measuring optical surface curvature radius is described. A new highprecision method for control of curvature radius of surface mirrors with a permissible error of the measurement less than 0,01 % of the nominal value is proposed and scientifically justified. An analysis is given of the output parameter of the functional circuit of the DWF-based instrument — the limiting radius of the recorded wavefront.
Keywords: curvature radius and shape parameters measurement, wavefront sensor, highprecision control, systematic measurement error
