The imaging requirements for 1000 line CCD camera systems include resolution, sensitivity, and field of view. In electronic camera systems these characteristics are determined primarily by the performance of the electro-optic interface. This component converts the electron image into a light image which is ultimately received by a camera sensor.Light production in the interface occurs when high energy electrons strike a phosphor or scintillator. Resolution is limited by electron scattering and absorption. For a constant resolution, more energy deposition occurs in denser phosphors (Figure 1). In this respect, high density x-ray phosphors such as Gd2O2S are better than ZnS based cathode ray tube phosphors. Scintillating fiber optics can be used instead of a discrete phosphor layer. The resolution of scintillating fiber optics that are used in x-ray imaging exceed 20 1p/mm and can be made very large. An example of a digital TEM image using a scintillating fiber optic plate is shown in Figure 2.

The article describes content of original and relevant but virtually forgotten thesis of V.V. Voronov on lighting of production site interiors by means of overhead natural (using three types of skylights) and artificial illumination, in order to elaborate scientific methodology for architectural design of more qualitative luminous environment on the basis of comprehensive approach and enhanced criteria framework of its evaluation using light engineering parameters. The thesis is unique in terms of the scope and quality of field and laboratory observations which are reflected not only in the text but also in the graphical attachments, namely photos, figures, schemes, drawings, charts, nomograms, and diagrams accompanied by specific measured or calculated parameters. The first part of the thesis contains theoretical basics and results of field observations conducted by different methods. This second part is the exposition of chapter 3 of the V.V. Voronov’s candidate thesis (1985). It describes the methodology for and the results of the experiments by means of planar and volumetric light simulation using the architectural lighting simulating assembly (chamber) which were conducted in MARKHI in 1970–1985.

This paper considers the fundamental problem of artificial lighting in various types and scales of industrial facilities, focusing on exterior lighting design solutions. There is a lack of interest from investors, customers and society in high­quality lighting design for industrial facilities in Russia, which in many cities are very imaginative structures, practically unused in the evening. Architectural lighting of various types of installations is illustrated with photographs. The purpose of the article is to draw attention to the aesthetic value of industrial structures, provided not only by the architectural, but also by a welldesigned lighting solution.

Instructional/Communication Technology has come to mean, in a narrowsense, media hardware or a set of tools enabling human beings toovercome their physical limitations. Etymologically, it means one or moretechniques, both concrete and abstract, that help human beings solveproblems. By extension, instructional technology (IT) means all tools atour disposal for facilitating learning. Tickton (1971) defines the purporeof IT as making "education more productive and more individual, to giveinstruction a more scientific base, and to make instruction more powerful,learning more immediate, and access more equal." While the technologyitself might be neutral as a medium and as a means of instructional communication,it is the natw of its use, in terms of timely and appropriatemessages, that is the key to understanding its consequences. It is this finalfactor upon which society needs to focus.The tecent combination of computer, video, fiber optics, satellite television,and other state-of-the-art technologies has enabled a small groupto control the lives of billions. Instructional technology has also Meritedits own share of this instantaneous global power. As a result traditionalboundaries between IT and mass media communication have blurred somuch that IT sounds like a misnomer.It has now become a platitude to say that the nation that controlledthe sealanes in the nineteenth century, or that controlled the airways inthe twentieth century, controlled the whole world. In the twenty-first century,it appears that whoever controls the airwaves will control the worldand whatever is beyond it. Thus the most explosive confluence of ...
