The controlled out-diffusion method was employed to induce a nuclear reaction in a palladium (Pd) plate with a MnOx film. The time-resolved mass spectra for Pd deuteride revealed tritium (T) production during the outdiffusion experiment. Similar time behaviors of mass number 1-4 and 6 in the spectra was also observed for Pd hydride. Film blackening was observed for most Pd deuteride as well as ...

This paper demonstrates that the pattern of silver particles embedded in the gelatin matrix of exposed and developed silver halide-based photographic film can serve as a template in a broadly applicable method for the microfabrication of metallic microstructures. In this method, a CAD file is reproduced in the photographic film by exposure and developing. The resulting pattern of discontinuous ...

The "RAD" (Radiation Assay Device) SEM experiment consists of two parts: a set of passive radiation dosimeters and several rolls of high speed color photographic film. The experimental package was flown on two separate high inclination shuttle missions, STS-85 (57) and STS-91 (51). The goal was to accurately measure the amount and type of radiation exposure to a typical payload in low earth orb...

Film grain is the unique texture which results from the silver halide based analog photographic process. Film emulsions are made up of microscopic photo-sensitive silver grains, and the fluctuating density of these grains leads to what is known as film grain. This texture is valued by photographers and film directors for its artistic value. We present two implementations of a film grain renderi...

A discussion of what a hologram is and how it is made is followed by a detailed procedure describing how to determine whether a proposed holographic system will be successful. Particular attention is given to the formation of the fringe pattern as it is the delineation of the fringes which determine the requirements and quality in holography. Several holographic systems are discussed giving the...

A circular grating is photographed through a phase object which deforms the image of the grating lines. By superimposing these deformed lines with a master grating on photographic film, mpire'' patterns are observed. These patterns are interpreted as fringes of constant radial derivative. https://ntrs.nasa.gov/search.jsp?R=19730011754 2017-09-12T18:22:28+00:00Z

Let’s design a simple camera system – a system that can record an image of an object or scene in the 3D world. This camera system can be designed by placing a barrier with a small aperture between the 3D object and a photographic film or sensor. As Figure 1 shows, each point on the 3D object emits multiple rays of light outwards. Without a barrier in place, every point on the film will be influ...

Most cardiovascular laboratories utilizing 35-mm cineradiographic techniques have the difEculty of not being able to project angiographic films to large audiences. One commercially available cineradiographic projector (Tagarno 35) provides relatively small images projected onto its own screen. When the screen is removed and the film is projected onto larger screens, a great deal of distortion t...
