Widestock Exposure Modification, Kurt D. Roberts Apr 1980

Widestock Exposure Modification, Kurt D. Roberts

Theses

A system exists for the exposure of large pieces of sensitized material. The strips are exposed, processed, and viewed by transmitted light. This procedure is used to gauge the quality of the film coating process. There are three problems with the existing system: uneven illumination, the timers do not take into account light decay, and finally, the operators, on occasion, set up the wrong conditions for an exposure. The purpose of this thesis is to modify an existing process for the automated exposure of wide stock strips. These modifications are to replace the system's components with state of the art, …

Halftone Dot Method For Image Evaluation Of High-Resolution Films Applied To Vesicular Film, Mark Gulden Apr 1980

Halftone Dot Method For Image Evaluation Of High-Resolution Films Applied To Vesicular Film, Mark Gulden

Theses

A feasible technique for deriving the spread function and modulation transfer function of a vesicular film has been determined. This technique is based on a method described by R. Byer which does not require the use of a microdensitometer, but only that of a "macro" densitometer. The method utilizes the fact that a halftone dot will change in size as a function of exposure. The spread function of the vesicular film was approximated with a mathematical model. The results, although favorable in many ways, are not conclusive. Some of the advantages and disadvantages associated with this technique as applied to …

Effect Of Iodide On Absorption Spectra For Dyes Adsorbed To Silver Halide Substrates, Mark Hinz Apr 1980

Effect Of Iodide On Absorption Spectra For Dyes Adsorbed To Silver Halide Substrates, Mark Hinz

Theses

The effects due to iodide in a silver bromide octahedral crystal on the absorption spectra of adsorbed 3,3'-Diethyl-9- Methylthiacarbocyanine and 5,5'-Dichloro-3,3',9- Triethylthiacarbocyanine were investigated. It was found that iodide encouraged Ja-band aggragation for 5,5'-Dichloro-3,3;9-Triethylthiacarbocyanine but not for 3,3’-Diethyl-9-Methylthiacarbocyanine. The suggestion is made that iodide is acting as nucleation centers for 5,5'-Dichloro-3,3',9-Triethylthiacarbocyanine.

Psychophysics Of The Measurement Of The Distance Between Two Negative Ticks, Two Positive Ticks, And Two Edges, Alan Coble Apr 1980

Psychophysics Of The Measurement Of The Distance Between Two Negative Ticks, Two Positive Ticks, And Two Edges, Alan Coble

Theses

The research that has been done deals with the increase in the precision of measurement under low magnification. There were four factors used in the field of view of a microscope to attempt an increase in precision. The factors were 10X and 20X magnifications, light intensities, and Kodak Wratten filters Nos. 58 and 45A. The precision of measurement was increased in the positive ticks and edges with factors other than high magnification.

Design, Construction, And Verification Of A Photographic Color Paper Sensitometer, Daniel Marc Denkin Apr 1980

Design, Construction, And Verification Of A Photographic Color Paper Sensitometer, Daniel Marc Denkin

Theses

The thesis problem is to produce a sensitometer to expose photographic color paper to be used as control strips in a photographic color paper process. This problem involves designing, constructing, and verifying the sensitometer. Designing the sensitometer is done by looking at different methods of exposing each dye layer of a photographic color paper. These methods include: fiber optics or light guides, light integrating devices, and projection systems. The method which was chosen for this experiment is the projection system. After the method had been decided upon, a lamp model will be calculated using the spectral sensitivity curve of a …

Increased Image Resolution And Film Efficiency Via Vacuum Platens And Other Mechanical Devices, James A. Ruffing Apr 1980

Increased Image Resolution And Film Efficiency Via Vacuum Platens And Other Mechanical Devices, James A. Ruffing

Theses

With an appropriate lens, focusing arrangement, film and processing, motor driven 35mm cameras will attain resolutions of hundreds of line pairs per millimeter. The combination of a narrow depth of focus, unusually thin films, a relatively large film gate and rapidly advancing films can produce imagery with less than optimum resolution across or within individual frames. A vacuum platen and an additional styrene pressure plate were fitted to a motorized 35mm camera in an effort to insure the film lies flat. Continuous vacuum pulling mechanisms, suction and induction, were evaluated. Each system's simplicity, portability and statistically analyzed imagery were assessed. …

Ultrasonic Flaw Detection, Wayne Buchar Apr 1980

Ultrasonic Flaw Detection, Wayne Buchar

Theses

An ultrasonic microscope was designed and constructed to detect surface flaw defects on materials which contain natural discontinuities. The application of this flaw detection system to via-fill defects of single layer multiple layer ceramic substrates was considered. The microscope was evaluated for its depth sensitivity and resolution capabilities. The results of the experiment are that the ultrasonic system has repeatable depth sensitivities of better than ten microns, and resolution capabilities on the order of 3.3 cycles per millimeter. The application of the flaw detector to ceramic substrate via-fill defect inspection was verified.

A Microprocessor Based Control System For An Electric Vehicle, Ronald C. Moffatt Mar 1980

A Microprocessor Based Control System For An Electric Vehicle, Ronald C. Moffatt

Theses

The control system described in this thesis is a low cost system designed to control the speed of an electric vehicle by adjusting the speed of a compound wound DC motor. The speed control method developed in this system is a combination of battery tapping, for control of the armature voltage, and pulse width modulation for field control; both generated by a microprocessor. Using a microprocessor, the control system is readily adaptable to a variety of motor voltages and motor control techniques by modifying the internal firmware of the processor. Overcurrent protection is included to prolong battery and motor life. …
