Abstract:
A method and a device for measuring the topography and/or the gradients and/or the curvature of an optically active surface of an object are disclosed. The device allows the object to be arranged in a receiving region with a contact surface for contact with the object. Inside the device, there is a plurality of point light sources that provide light that is reflected at the surface to be measured of an object arranged in the receiving region. The device includes at least one camera with an objective assembly and an image sensor for detecting a brightness distribution which is produced on a light sensor by the light of the point light sources reflected at the surface to be measured.

Claim (Index 1):
A method for measuring at least one of a topography, a gradient, or a curvature of an optically effective surface of an article, the method comprising:\n iteratively performing:\n reflecting light emitted by one or more light spots at the optically effective surface of the article to be measured; \n capturing a brightness distribution of the reflected one or more luminous spots; \n assigning the brightness distribution to the light spots causing the brightness distribution; \n predetermining a first topography; \n determining reflection locations on the article for the light emitted by the light spots; \n calculating surface normals {right arrow over (n)} at the reflection locations for the light emitted by the light spots; and \n calculating a further topography of the article by fitting local basis functions of the optically effective surface being modeled as a linear combination of the local basis functions; \n up to a convergence criterion; and\n establishing at least one of an absolute position or a relative position of at least one point on the optically effective surface of the article to be measured in a coordinate system that is fixed relative to an apparatus.
