Studies On The Lith Development Of A Silver Iodobromide Emulsion, Larry Zurbrick Oct 1979

Studies On The Lith Development Of A Silver Iodobromide Emulsion, Larry Zurbrick

Theses

The lithographic development of a silver iodobromide emulsion with thiocyanate substituted for bromide in a lith developer formulation showed differences in behavior with regard to induction time and maximum rate of development at equal levels of normality. An experiment was designed with development time, halide concentration, and exposure level as the variables with maximum rate of development, time to reach 0.20 optical density (induction time), and slope at 0.40 optical density as the response parameters. The maximum rate of development with the developer containing bromide was found to be significantly dependent upon exposure level and not significantly dependent upon bromide …


Electric Field Enhancement Of Efficiency In Autoradiographic Exposures, Harvey Smith Oct 1979

Electric Field Enhancement Of Efficiency In Autoradiographic Exposures, Harvey Smith

Theses

An external electric field was applied during autoradiographic exposures in an attempt to influence the path length and trajectory of image forming beta particles. Various techniques were employed to maximize the electric field applied. No evidence was found for increases in efficiency of image formation within the receiving emulsion, up to a field strength of 7 x 10 volts/cm.

Modulation Transfer Function Of Image Motion Due To Operator Vibration, Venkatraman Nagaswami Sep 1979

Modulation Transfer Function Of Image Motion Due To Operator Vibration, Venkatraman Nagaswami

Theses

The displacement path of a hand-held photographic camera is studied at low shutter speeds when operated by different observers. Using the Fourier method, the average power spectrum of hand vibration is obtained. The Modulation Transfer Function of image motion for an average observer at various exposure times is theoretically predicted.

A Low Frequency Sine Wave Camera, Russell Palum Jun 1979

A Low Frequency Sine Wave Camera, Russell Palum

Theses

An optical system using spherical and cylindrical optics can convert area-modulated spatial sinusoidal targets to intensity-modulated spatial sinusoidal images. A specific system was analyzed with a spot diagram. System response to 30 cycles-mm~l is predicted. The system mechanical tolerances were determined on the basis of modulation transfer function (MTF) calculations. A mechanical structure which would maintain these tolerances was designed and built.


The Effects Of Sulfur Sensitization And Stabilization By 4-Hydroxy-6-Methyl-1,3,3a,7-Tetraazaindene On Hydrogen Sensitization Of A Photographic Emulsion, David Lyon Jun 1979

The Effects Of Sulfur Sensitization And Stabilization By 4-Hydroxy-6-Methyl-1,3,3a,7-Tetraazaindene On Hydrogen Sensitization Of A Photographic Emulsion, David Lyon

Theses

Hypersensitization using H2 gas is the most recent addition to the techniques available to reduce the effects of low intensity reciprocity law failure. Because of the presence of addenda in all commercially available emulsions, the interactive effects of hydrogen sensitization with a common stabilizer (4-methyl-6-hydroxy-1,3,3a,7-tetraazaindene) and a common form of chemical sensitization (Sulfur Sensitization) alone and together were investigated. A primitive, single jet emulsion was coated with and without the above addenda. Samples were paired and either treated to a hydrogen baking process at 65°C for 20 minutes, or left untreated. Sensitometric exposures were made in a room air environment …


Design And Evaluation Of A Stepped Diaphragm Intensity Scale Graphic Arts Sensitometer, Patrick Meehan Jun 1979

Design And Evaluation Of A Stepped Diaphragm Intensity Scale Graphic Arts Sensitometer, Patrick Meehan

Theses

An Intensity Scale Sensitometer for testing the photographic response of Graphic Arts materials was built and evaluated. The sensitometer utilizes a stepped area diaphragm and a cylindrical lens to produce a stepped illuminance distribution at the film plane. Both tungsten and pulsed xenon lamps are provided. A computer aided study was used to find the optimum lamp position with respect to the reflector. A scanning aperture type shutter located at the stepped diaphragm and a knife edge aperture located at the lens are used to control exposure duration and intensity. The main advantage of this sensitometer is the production of …


The Modification Of Simple Images By Fourier Transform Manipulation, Noel Chavez Jun 1979

The Modification Of Simple Images By Fourier Transform Manipulation, Noel Chavez

Theses

Knowledge of how an image is changed by a given modification of its Fourier transform is important when attempting to find solutions to problems in image processing. Several types of filters were used to modify the Fourier transforms of an edge and a bartarget. The images were reconstructed from the modified transforms to determine the change produced by a given modification. Various regions of the Fourier transform determine specific characteristics of the image. The amplitude of the low frequencies controls the form and average level of the image, while the amplitude of the high frequencies effects sharp transitions and noise.

Comparison Of Bromide, Benzotriazole, And Phenyl Mercaptotetrazole And Their Effect On Photographic Development, James Kretchmer May 1979

Comparison Of Bromide, Benzotriazole, And Phenyl Mercaptotetrazole And Their Effect On Photographic Development, James Kretchmer

Theses

A comparison of three commonly used antifoggants was made. Their effect on the formation of fog and image density development was studied using a rate factor of development. This rate factor is defined as the slope of the curve for density-log development time. Bromide and benzotriazole were found to have no effect on the rate of development whereas 1-phenyl-5-mercaptotetrazole was found to significantly reduce the rate of development. Bromide and benzotriazole were found to cause a suppression of image density only by increasing the time before density formation begins.


Minimization Of Unwanted X-Ray Exposures On Conventional Photographic Films By Developer Modification, Michael L. Rudolph May 1979

Minimization Of Unwanted X-Ray Exposures On Conventional Photographic Films By Developer Modification, Michael L. Rudolph

Theses

Experiments were done to reduce the influence of unwanted X-ray exposures on Kodak Plus-X film. Variations of surface developer components showed no favorable results. The concentration of KBr was varied up to 10 grams per liter with again, no favorable results. The incorperation of benzitriazole decreased base plus fog from values of .81 to .56 with a significant decrease in speed. Phenyl mercaptotetrazole was extreamly effective in decreasing both base plus fog and speed.
