This paper describes a projection system using DLP projectors and parabolic mirrors to provide a 90 degree curved screen with a 4 to 1 aspect ratio. This display is intended to provide an "immersive" experience for the user and facilitate a very large canvas on which to utilize multiple applications or single ones requiring a large screen. The resulting display has a 3072 x 768 pixel display area.
Optics has been a technology for a long time. Often, just when it looked like the technology was beginning to diminish in impact, a new technology related to optics was born and completely rejuvenated the field. This caused significant innovation in relatively short periods of time. For example, the development of the laser in the early 1960s gave rise to laser printers, CD disk drives, optical recording, fiber optic communication etc. and has produced an enormous increase in practical devices as well as economic value. We are now faced with another opportunity. This opportunity is the ability to fabricate small optical "benches" or structures using the same material that has enabled the computer revolution, viz. silicon. While this field is relatively new, what might we expect from this new capability? The opportunity for displays, sensors, communication, etc. are beginning to open up and present new business and innovation possibilities. Optics has always benefited from system enabling technologies and Micro-Electro-Mechanical-Systems is a major new development. In this paper I will look at where we might go with Optics and MEMS or MOEMS. Examples of display concepts, etc. will be discussed that illustrate the great potential of these combined capabilities in just one area. It is likely that we will not be limited by the technology but by our imagination in its use.
Electronic printing is now 25 years old. A great deal of progress has been made as evidenced by the great number of electronic printers and their associated technologies. This paper illustrates three simple metrics with which to analyze electronic printer technology. The metrics are not necessarily intended to be anything profound or deterministic but appear to illustrate some relative constants as well as significant improvements in printers that indicate a trend whose final outcome is yet to be seen. Since electronic printers are basically information delivery devices, they can be analyzed as to their information delivery capability on a cost-performance basis. The three metrics utilized in this paper involve a number of characteristics such as printer weight, speed, spatial printing density and color. Over 170 printers area used in this analysis dating from the birth of the laser printer in the mid-1970s up to the present time. This metric oriented view of the technology may give us some insight as to where the electronic printing industry is going on a cost/performance basis as well as where new products should be aimed so that they provide the desired market impact.
Color devices have become commonplace to many users including those at home. The color revolution began about 1990 with the ready availability of color displays and affordable color printers.
Since the mid-1970s, electronic printing has been available to businesses. Its growth has been truly amazing. Original predictions of a need for no more than 500 laser printers has now given way to millions of printers of all types from home and personal office to the print shop. This paper is intended to look at what the future of electronic printing might look like. Any prognostication of the future is always risky and the intent here is to look at what has happened and what is happening in the marketplace and thus get some view of the future. Will the printer vendors of today be the printer vendors tomorrow? What will be the market leading characteristics of future electronic printers? Can we measure value to the first order? We shall try to briefly explore these and some other questions in order to pursue some idea of where the business is going.
The use of color imaging devices continues to rapidly expand as the use of personal
computers grows. Understanding the characteristics of color imaging devices such as
displays, scanners, dig:ital cameras, printers etc. is key to their proper use. The purpose of
this report is not to delineate all of the varied aspects of these devices but to concentrate on
one interesting aspect, viz. color volume. The many other aspects that could be discussed
such as gray scale range, density range, page size, colorant stability, etc. are also important
but for the purposes of this report, only color volume is going to be discussed.
Since their earliest market presence in the mid-
19705, xerographic printers have been a
valuable asset to the information marketplace.
The year 1991 was no exception. Many
improvements, enhancements and innovations
in xerographic printers were presented by a
host of vendors.
In this paper, the author explores several key electrophotographic printer (ELP) improvements as well as significant new product offerings. The intent is to include only those printers with major technology and/or market impact potential. In order to provide a reasonable taxonomy of features, the author provides ELP trends in the categories of speed, both higher and lower; image quality; controller and page description language enhancements; integration and system trends; and a brief look at marking system improvements. Lastly, a performance metric has been included to show where ELP technology has gone in the last few years.
