Latest Patents

Herve Chardron holds 1 patent for a device designed to assess the brightness of a surface. This device includes a light source that sends an incident beam onto the surface, along with a polarizer and two analyzers. One analyzer analyzes the reflected light, while the other examines the diffuse reflection from the surface at a selected point of incidence. The device features light-sensitive photodetector means to receive light from the analyzers. The incident light impinges on the surface at an angle between 0 degrees and 90 degrees, with the incident beam polarization being perpendicular to the plane of incidence. The analyzers are strategically located to differentiate between parallel and perpendicular polarization, allowing for a more precise assessment of specular and diffuse brightness.
