DEVICE AND METHOD FOR MEASURING SHEETS, MORE PARTICULARLY WINDSHIELDS OF VEHICLES

摘要

The invention relates to a device for measuring sheets (16) comprising a light source (14) and a light sensor (21), which are arranged such that a light beam (15) emerging from the light source (14) passes through the sheet (16) and impinges on the light sensor (21). According to the invention, the light sensor (21) has a dynamic range of more than 8 bits with linear resolution. The invention also relates to a corresponding method. The invention makes it possible to reliably measure both a primary beam and a secondary beam of the light beam that passed through the sheet (16).
