    "abstract": "Silver halide emulsions for the direct recording of oscillograph traces represent a new development in the photographic industry. These emulsions will form an immediately visible image at writing speeds up to 10 in./sec when a super-high-pressure mercury arc is used as the light source. With the same source a latent image is formed at writing speeds up to at least 40,000 in./sec. Such latent images can be made visible within a fraction of a second by secondary exposures. The exposure which forms the image is a very intense radiation of wavelengths absorbed by the silver halide or it may be x-rays, gamma-rays or an electron beam, while the amplifying exposure is light-absorbed by the silver halide and is of moderate intensity. Good contrast between image and background and good stability of the background depend on the extreme reciprocity-law failure of these special emulsions, combined with their ability to be desensitized by low-intensity light. The contrast itself depends on the difference in light absorption between the silver of the image and nonimage areas. Properties of these direct-recording papers and mechanisms by which they function are discussed.",
