Laser Imaging With A Holographically Produced Lens, Eric Schwartz Aug 1977

Laser Imaging With A Holographically Produced Lens, Eric Schwartz

Theses

A process is outlined by which a hologram has been produced for use as an imaging device in a laser machining apparatus. Such a hologram has been termed a hololens. The hololens was initially produced by recording the interference between a coherent plane reference wave and an object wave which was produced by passing a plane wave through a transparency. The recording film was positioned at Brewster's angle and the laser light was polarized normal to the surface of the glass plate substrate in order to reduce optical noise caused by interference between the recording beams and their reflections. This …

Thermalhardening Offset Lithographic Printing Plate, Eric Leonard Jun 1977

Thermalhardening Offset Lithographic Printing Plate, Eric Leonard

Theses

Offset lithographic printing plates, until several years ago, used incoherent light sources for image creation in light sensitive coatings. These light sources are primarily in the ultraviolet light region. Image creation, using an incoherent light source, requires either a film negative or positive and long exposure times. Exposure time is dependent on the sensitivity of the light sensitive coating and the light intensity. In recent years both equipment and plate suppliers have been working to develop offset lithographic printing plates which use coherent laser light for image creation. To date all recorded developments have worked on light hardening image creation …


An Investigation Into The Effects Of Gloss And Smoothness On Legibility, Donald Perlman Jun 1977

An Investigation Into The Effects Of Gloss And Smoothness On Legibility, Donald Perlman

Theses

This study on legibility takes a different approach than the studies that precede it. Standardized test targets (ISO Characters) were used as the measurement device instead of the various means used previously. This was done to keep the test more objective. Twelve papers of different gloss and smoothness values were tested with two groups--college students and senior citizens. These experiments were done under controlled conditions with the only variable being the paper. The average results from the legibility readings were correlated against the physical properties of the paper samples. The results of this study showed a 2 and 4% correlation …

Infrared In-Process Densitometer, Miroslav Piskacek Jun 1977

Infrared In-Process Densitometer, Miroslav Piskacek

Theses

The development chamber for an infrared, in-process densitometer, which will monitor and display a characteristic curve of a standard sensitometric strip during development, was designed. The monitoring radiation is to be emitted by a sequentially pulsed array of IR diodes (RCA SG1009A) and detected by an array of solid state detectors (UDT-450 Photodiode/Amplifier combination). The output of the detectors, corresponding to IR transmission, is to be scanned, electronically converted into density, and displayed. Electronic scanning assures that processes with subminute total development time can be monitored. Optical losses of the system were estimated, and a model of the optical system …


Direct Measurement Of The Optical Modulation Transfer Function Of Non-Developed Emulsions, Glen Elie Jun 1977

Direct Measurement Of The Optical Modulation Transfer Function Of Non-Developed Emulsions, Glen Elie

Theses

A new procedure for measuring the MTF of non-developed emulsions is discussed, which uses a coherent energy source and interference system to produce sinusoidal fringes on a film sample. The transmitted light is projected onto the scanning slit of a photomultiplier, and its variations registered on a chart recorder. Measurements are taken directly from the traces of the irradiance distribution to calculate the optical part of the MTF of the sample. This system does not require development of the film, and is therefore free of the non-linearities inherent in traditional test methods. Results are obtained for Kodak Panatomic-X, Kodak High …

Image Intensification By Superimposed Vesicular Images Generated By Decomposition Of Hydrogen Peroxide, William Grabenstetter May 1977

Image Intensification By Superimposed Vesicular Images Generated By Decomposition Of Hydrogen Peroxide, William Grabenstetter

Theses

In the late 1960's, Weyde discovered that treating conventionally processed silver halide films with hydrogen peroxide led to intensified densities by the superimposition of vesicles at the silver image sites. This project attempted to reproduce the results of 5° - 10°DIN speed increase and excellent sharpness mentioned in the patents issued to Weyde. Using the patents as a reference, a paste of urea hydrogen peroxide and PEG was examined as an image intensifier, with no success. Alternate binders suggested in the patents were then examined, Triton X-405 proving to be the best. A paste of 4g. urea hydrogen peroxide in …

Copper Physical Development Of Copper Latent Images, Gregg Tashker, Peter Schreiber May 1977

Copper Physical Development Of Copper Latent Images, Gregg Tashker, Peter Schreiber

Theses

Copper physical development of copper latent images was researched. The proposed method for producing copper latent images was to soak a titanium dioxide in a copper (II) sulfate nucleating bath and expose to UV radiation below 4l0nm. The exposures were to produce the copper latent image. Three physical developers were used to try to intensify the latent images. The developers utilize an iron (II)/iron (III) redox system to reduce copper (II) sulfate to copper metal. The developers also contain carboxylic acids as complexing agents for iron (III) ions and cationic surfactants for stability. The printout achieved was not stable and …


Mtf And Adjacency Effects Of Vesicular Film, Timothy Sewell, Paul Willig May 1977

Mtf And Adjacency Effects Of Vesicular Film, Timothy Sewell, Paul Willig

Theses

The Modulation Transfer Function and adjacency effects are important measurements of a photographic material. For vesicular film it is of interest to investigate the MTF and adjacency effects with relation to the three variable parameters, development temperature, exposure and development time. This investigation clearly shows that adjacency effects do occur in vesicular film, and that exposure and development temperature are important factors in determinating the film MTF.
