  • Is photographic film made of grating or optical fiber

    Is photographic film made of grating or optical fiber

    Photographic film a sheet of plastic (polyester, celluloid (nitrocellulose) or cellulose acetate) coated with an emulsion containing light-sensitive silver halide salts (bonded by gelatin) with variable crystal sizes that determine the sensitivity or resolution of the film. The sizes and other characteristics of the crystals determine the sensitivity. This is because this type offiber permits the construction of guided wave interferometers directly from the fiber itself. Interferometers can be used to measure small phase changes in light transmitted through the sensing region. What is orthochromatic film? Orthochromatic film is a type of black and white film which is not sensitive to red light, but only to green and blue light. What. Motion picture film is inherently unstable, consisting of many different and complex layers.
