Problems solved by technology

But the duration of the measurement of the facing face is important, and positioning the measurement of the first face relative to the second face has always been difficult
Furthermore, point-by-point measurement generally requires extremely precise means for moving (mechanical or optical) the position of the probe, which makes it relatively expensive to acquire and repair and difficult to deploy on industrial sites

Embodiment Construction

[0039] It should be understood that the numerical values ​​and descriptions of the present invention have been simplified to show related elements for a clearer understanding of the present invention. At the same time, for clarity purposes, the measurement method based on the surface of the reproduced optical component is omitted. Many other components found. However, since these elements are well known in the prior art, a detailed discussion of these elements is not envisaged here. This disclosure addresses all these changes and modifications known to those skilled in the art.

[0040] figure 1 A flow chart including 5 steps of a procedure for measuring the geometric structure of a component according to an embodiment of the present invention is presented. In the following, the five steps are explained and detailed with respect to the measurement of the geometric structure of the spectacle lens, which includes a first surface 10 (for example, convex surface) and a second surfac...

Abstract

The method involves measuring (S1) a signal (MS1) from conversion of a probe signal by a side of an optical component, and measuring (S2) another signal (MS2) resulting from another conversion of another probe signal by another side. A third conversion is determined (S3) to convert a set of coordinates (R1) to another set of coordinates (R2). The sides are estimated (S10) by using the former signal and the latter signal, simulation of conversions and cost criteria quantifying difference between the former estimation and the former signal and between the latter estimation and the latter signal. An independent claim is also included for a system for measuring a geometric structure of an optical component.

Description

Technical field [0001] The subject of the present invention is a method and system for measuring the geometry or optical structure of an optical component. [0002] The method according to the invention makes it possible to measure both sides of the optical component in an absolute manner. Absolute measurement is intended to refer to a measurement that does not require any prior knowledge of the component (other than its refractive index). Surface measurement is susceptible to many industrial applications. It is particularly useful for the inspection or measurement of spectacle lenses in the field of ophthalmology; in this case, the production of composite surfaces requires simultaneous determination of several hundred coefficients. Background technique [0003] This section is intended to introduce the reader to various aspects of the field that may be related to the various aspects of the invention described and / or claimed below. This discussion is believed to be useful to pro...
