A discussion of the "Lunar Television Image Converter" (Lunar-TIC) will be presented. This is the system utilized for the digital processing of the RANGER and the MARINER pictures. Digitizing requirements and 'tradeoffs' will be covered as they apply to this process which employs a magnetic analog tape as the data source, converts the data for processing in a 7094 computer and then converts it to picture form. Some of the RANGER and MARINER pictures which have been processed in the IPL digital computer will be shown and the various techniques used will be discussed. Samples will also be shown of the capability of Lunar-TIC to scan, digitize, and reconstruct photographic transparencies.
A towed deep ocean photographic system in continuous use and development at the U.S. Naval Research Laboratory has produced well over 100,000 bottom photographs. Details of this system, including the arrangement of lights and cameras, the use of longer ranged sensors to regulate camera operation, and the shipboard processing techniques, are described. Some proposed future improvements in the system are also presented.
Irradiation exposure, contamination, and high energy levels present problems not usually associated with biological and thin section autoradiography. The need for autoradiographs of highly radioactive specimens has made it mandatory that techniques be developed which can produce high resolution autoradiographs remotely in hoods and/or hot cells.
An historical outline will be given on the development of theories of image formation in the microscope, particularly how to make transparent objects under the microscope visible to the eye or camera. Technical aspects of design will be discussed, as well as light sources, the microscope, the camera, film, and the application of such films for instruction and education in Microbiology. Slides of different instruments for cinemicrography will be shown.
The transformation of a hardware research and development. project to a production program which meets the lead time and cost demands of a dynamic market can be a complex and challenging problem. This is particularly so when the need of the market and the pressure of competition force the acceler ation of full-scale production while certain of the basic engineering design tasks are still in progress. Rigorous coordination between engineering, production, and marketing functions is essential both to avoid costly rework and to maintain an orderly and predictable production schedule. This paper will describe how this transition was accomplished in the successful introduction of the VARISCAN, an advanced photo-interpretation tool developed by the Nuclear Research Instruments Division of the Houston Fearless Corporation, to meet an exceedingly demanding market. In this instance, the normally sequential phases of design development, prototype construction and evaluation, production engineering, and finally full-scale production were compressed into an abnormally short time span, enabling first deliveries of the production item just four months from start on work on the prototype. Within an additional fourteen months, deliveries of fifty-one production units were completed, with full-scale production of an additional fifty units of a significantly improved model already in progress. We consider this experience to be well worth recording, as its value in demonstrating what a dedicated, skillful, and sometimes ingenuous management and technical tesm can accomplish will unquestionably provide "fallout" benefits to future programs of this type.
