 According to the definition of curvature, the distance between the image of curvature center and surface image is the radius of curvature of the sphere.

    As shown in Figure, the left is the positioned image of spherical center of the tested object, and the right is the positioned surface image of the tested object. Displacement transducer will record the distance R between the two images, and R is the radius of curvature of the tested object.
