Title: The Innovations of Patrick Bertrand
Introduction
Patrick Bertrand is a notable inventor based in Issy-les-Moulineaux, France. He has made significant contributions to the field of optical measurement and deflectometry. With a total of 2 patents, his work focuses on advancing the technology used in optical components.
Latest Patents
One of his latest patents is the "Fringe Deflectometry Apparatus and Method." This innovative apparatus illuminates an optical component using radiation with a known wavefront. It deflects the radiation after it has been reflected or transmitted by the optical component, materializing a reference ray. The transverse aberration of the reference ray is then measured, allowing for an absolute phase reference to be provided through a deflectometry method.
Another significant patent is the "Optimization Method and Device for Direct Measurement of an Optical Component." This method and device are designed for measuring the geometrical or optical structure of components such as lenses. The process involves illuminating the optical component with incident light, measuring the wavefront slopes after reflection or transmission, and deducing the surface topography or refraction index map from these measurements. The calculating procedure includes initializing a result surface and optimizing it through various steps to minimize the departure from the surface to be measured.
