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.

Theses
Conditions for producing the Sabattier effect in Eastman fine grain release positive 5302 film were established. Modifications of the second developer to develop more internal latent image by the addition of potassium iodide or to increase solution ~ physical development by the addition of sodium thiocyanate and sodium sulfite were performed. These modifications made no significant change in the Sabattier effect. When chemical fog (from sodium borohydride) was substituted for the exposure during development, no reversal corresponding to the Sabattier effect was obtained.
