Method for measuring the optical quality of a given area of glass material, and related measuring device

摘要

Optical quality measurement methodsPage ofA zoGlass data, related measuring deviceOne aspect of the invention relates to a method for measuring the optical quality of a specific area (13) of a road or railway vehicle glass (10) to be positioned in an optical path of an image acquisition device, The measuring method is implemented by a measuring device (40) including a transmitter (41) and a wavefront analyzerA step of emitting a light beam from a transmitter (41) to the specific area (13),The step of analyzing the wavefront of the light transmitted through the given area (13) by a wavefront analyzer comprises:Wave front error map generation sub step,A sub step of determining at least one optical defect pattern existing in the region (13) of the glass (10) from the wavefront error pattern.Figure published with summary: Figure 3
