Title: Alain Spang: Innovator in Optical Wave Inspection Technologies
Introduction: Alain Spang, a talented inventor based in Vence, France, has made significant contributions to the field of optical wave inspection. With a patent to his name, he has demonstrated his expertise in developing advanced systems for analyzing the surfaces of optical waves.
Latest Patents: Alain Spang holds a patent for a "System for inspecting surfaces of an optical wave using a graduated density filter." This innovative system is designed to inspect the surface of an optical wave originating from an optical device, which includes an exit pupil. The inspection system features an optical measuring head and a computer that processes images captured by the optical measuring head. Notably, this measuring head incorporates a density gradient filter, with varying density periodic across two spatial dimensions. It also consists of a matrix frame housing four identical square-shaped lenses, symmetrically arranged and sharing the same focal length, along with a photodetector array. Each lens generates an image of the exit pupil within the plane of this array. The computer involved in image processing computes the partial derivatives of the wave surface, facilitating precise analysis.
