In this thesis, several kinds of spherical curvature measurement methods are introduced, and the "arch-high and chord-length method" is selected after introduction of the existing methods, and then the novel type of instrument for measuring spherical curvature with the variable ring is developed. In research, the grating sensor, integrated circuits and other new technologies are adopted and integrated. As a result of this, Its specific technical indicator is 0.1um in absolute accuracy, 0.01% in relative accuracy, and 0.001% in repeat accuracy.
