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

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.

The Role Of Reliability In The Publisher/Supplier Relationship In Textbook Production, Steven Brenner
The Role Of Reliability In The Publisher/Supplier Relationship In Textbook Production, Steven Brenner
Theses
Most publishers in the textbook publishing industry experience production delays. If the delays are serious it could result in a postponed publication date. The ramifications of a postponed publication date range from anxiety to the author and publisher to lost revenues. Most textbook publishers are required to have their new texts reviewed by adoption committies, therefore it is imperative that their books be ready by a certain date. There are many functions involved in the book making process. A delay in any one area may hold things up in other areas, thus compounding the situation. The purpose of this thesis …

A Study Of The Effect Of Coating Variations On Tone Reproduction In The Association Products Plate, Mark Woodhouse
A Study Of The Effect Of Coating Variations On Tone Reproduction In The Association Products Plate, Mark Woodhouse
Theses
The halftone process is so much a part of printing today that it is often hard for printers to conceive of the notion of reproducing an image without a screen. Before the idea of breaking up an image into small dots came along however, printing was being done with lithographic methods which produced excellent results and the main concern of the theorist and technician was how to produce a more consistent, higher-quality, continuous tone image. Perhaps it is unfortunate that the advent of the halftone process distracted thought from this area to such a large degree, since it wasn't until …

A Low Frequency Sine Wave Camera, Russell Palum
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.
Determination Of The Chemical Spread Function Of Kodak High Contrast Copy 5069 Emulsion, J.N.A. Laitre
Determination Of The Chemical Spread Function Of Kodak High Contrast Copy 5069 Emulsion, J.N.A. Laitre
Theses
A new procedure for obtaining the Chemical Spread Function of an emulsion-developer combination is discussed. This procedure consists of directly measuring the Optical Modulation Transfer Function (MTFO) by scanning the sinusoidal object irradiance distribution through the non-developed emulsion using a microdensitometer. The Modulation Transfer Function (MTF) of the processed emulsion is determined in the conventional manner. Then the Chemical Modulation Transfer Function (MTFC) is determined from the linear relationship: MTF = MTFC X MTFO. Once the MTFO is determined then the Spread Function is calculated using the Fourier Transform operator. Photographic systems are in general non-linear. However it is well …
Design Considerations In Linear Microdensitometry, Thomas Lianza
Design Considerations In Linear Microdensitometry, Thomas Lianza
Theses
The conditions for linearity in microdensitometry are discussed. It is shown that under proper conditions a microdensitometer may behave linearly regardless of the coherence properties of the source. A linear microdensitometer was constructed and design considerations are presented as well as test results.
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 …
Image Quality Dependence On Partial Coherence In A Projection Printer, Bruce Radl
Image Quality Dependence On Partial Coherence In A Projection Printer, Bruce Radl
Theses
A study has been made of the printed images from a projection printer whose light source can be varied to provide illumination of various levels of partial coherence. The coherence interval for five light source configurations was measured with a shearing interferometer at the object plane of the printer. Many test images were made with the printer for each of the five degrees of partial coherence and results showing image quality as a function of coherence interval have been reported. It was found that with an 11µm coherence interval the image forming characteristics were typical of an incoherent instrument and …
The Modification Of Simple Images By Fourier Transform Manipulation, Noel Chavez
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.
Design And Evaluation Of A Stepped Diaphragm Intensity Scale Graphic Arts Sensitometer, Patrick Meehan
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 Effects Of Polyethylene Oxide On Dmaac's "B" Type Developer, Harold Mccullough
The Effects Of Polyethylene Oxide On Dmaac's "B" Type Developer, Harold Mccullough
Theses
This report describes the results of a study comparing ASA speed, contrast index, and resolution from a developer time series. The time series was made on six levels each of PEO-400, -600, -1000, and -1500 added to DMAAC's "B" developer. Kodak's SO-277, low contrast, and SO-243, high contrast, aerial duplicating films were used. Results show that PEO-400, at a concentration of 30ml/l, can be a material help in getting higher speeds and contrast index from SO-277 aerial duplicating film without loss of resolution.

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