Bernard Friedel

Bernard Friedel is a notable figure in the field of geometrical optics, which studies how light behaves as it travels through different media. His contributions often focus on understanding how lenses and mirrors manipulate light to form images. Friedel's work has implications for designing optical instruments, such as cameras and microscopes. He emphasizes the importance of ray diagrams, which visually represent how light rays interact with surfaces. This approach helps in predicting image formation, focusing, and other optical phenomena, making it easier to design devices that rely on light effectively.
