Title: **Didier Charlot: Innovator in Optical Devices**
Introduction
Didier Charlot, an inventive mind based in Paris, France, has made significant contributions to the field of optical devices. With a portfolio of three patents, he stands out as a noteworthy inventor. His latest innovations demonstrate a commitment to advancing technology in the realm of holography.
Latest Patents
One of Didier's most recent patents is a groundbreaking holographic process and device that utilizes incoherent light. This optical device is engineered to generate a signal based on the distance of an object from the device itself. The innovative design includes a first polarizer, a birefringent crystal positioned downstream from the first polarizer, and a second polarizer arranged downstream from the birefringent crystal. The second polarizer plays a crucial role in creating a pair of interferograms by adjusting the phase of the light. Two outputs are generated by separately integrating an amount of light from each of the pair of interferograms. Ultimately, these two outputs are combined to produce a signal that depends solely on the distance between the object and the optical system, showcasing Didier's ingenuity.
