Available in PDF, EPUB and Kindle. Book excerpt: An analysis of scan parameters as they affect the performance of electron bombardment induced conductivity (EBIC) targets is presented. The conclusion is reached that the secondary emission characteristic of the target surface is an extremely important parameter in camera tubes of the photoconductivity and EBIC types. Evidence that the electron absorptivity of the target for low voltage electrons is affected by the degree of induced excitation is presented. Results of an investigation of different EBIC target materials are reviewed. The fabrication of experimental EBIC tubes having electrostatic and magnetic focused image sections is described. Test results are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The content of this monograph stems from the writer's early involvement with the design of a series of television camera tubes: the orthicon, the image orthicon and the vidicon. These tubes and their variations, have, at different times been the "eyes" of the television system almost from its inception in 1939. It was natural, during the course of this work, to have a parallel interest in the human visual system as well as in the silver halide photographic process. The problem facing the television system was the same as that facing the human visual and the photographic systems, namely, to abstract the maximum amount of information out of a limited quantity oflight. The human eye and photographic film both repre sented advanced states of development and both surpassed, in their performance, the early efforts on television camera tubes. It was particularly true and "plain to see" that each improvement and refinement of the television camera only served to accentuate the remarkable design of the human eye. A succession of radical advances in camera-tube sensitivity found the eye still operating at levels of illumination too low for the television camera tube. It is only recently that the television camera tube has finally matched and even somewhat exceeded the performance of the human eye at low light levels. It was also clear throughout the work on television camera tubes that the final goal of any visual system-biological, chemical, or electronic-was the ability to detect or count individual photons.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a major resurgence in optics research and the teaching of optics throughout the major universities both in this country and abroad. Electrooptical devices have become a challenging form of study that has penetrated both the electrical engineering and the physics departments of most major schools. There seems to be something challeng ing about a laser that appeals to both the practical electrical engineer with a hankering for fundamental research and to the fundamental physicist with a hankering to be practical. Somehow or other this same form of enthusiasm has not previously existed in the study of photoelectronic devices that form images. This field of, endeavor is becoming more and more so phisticated as newer forms of solid state devices enter the field not only in the data processing end but in the conversion of radiant energy into electrical charge patterns that are stored, manipulated, and read out in a way that a decade ago would have been considered beyond some fundamental limit or other. It is unfortunate, however, that this kind of material has heretofore been learned only by the process of becoming an apprentice in one or more of the major development laboratories concerned with the manufacture of image intensifiers or television tubes or the production of systems employing these devices.
