Projection is a technology for generating large, high resolution images at a price point end users can afford. This allows it to be used in a wide variety of large-screen markets such as television and cinema. In addition, there are emerging small screen markets where a pocketable miniaturized projector can display images from mobile information devices such as smart phones or portable media players.Fully revised, this second edition of [start italics]Projection Displays[end italics] provides up-to-date coverage of the optical and mechanical systems in electronic projection displays. It takes into account major new developments in the many technologies needed to manufacture a projector display system. It presents a comprehensive review of projector architectures, systems, components and devices. Key new and updated features include: new material on light sources for projection displays; updated information on the human factors of projection displays including color gamuts, resolution and speckle; coverage of new image generating systems including LCOS and scanned laser systems; up to date information on front and rear projection screens; practical examples of projection display applications; models for predicting the performance of optical and mechanical systems This book is aimed at practicing engineers and researchers involved in the research, development, design and manufacture of projection displays. It includes key aspects from the many technologies contributing to projection systems such as illumination sources, optical design, electronics, semiconductor design, microdisplay systems and mechanical engineering. The book will also be of interest to graduate students taking courses in display technology and imaging science, as well as students of the many other engineering, physics and optics disciplines that lead into the field of projection displays.read more

Modeling diffractive effects due to micro-lens arrays on liquid crystal panels in projectors
TL;DR: In this paper, the authors use a mixed-level optical simulation methodology, which unifies the use of rigorous EM wave-level and ray-level tools for analyzing projector performance, which can potentially lead to more accurate performance than that from individual modeling tools alone.
Proceedings ArticleDOI
Display color synthesis in the space-time continuum
TL;DR: The argument that the continued evolution of display technology toward higher display resolution and enhanced color quality has exposed the limitations of both spatial color synthesis and temporal color synthesis raises questions as to whether either method for synthesizing color can alone fully satisfy the ever increasing demands on display image quality.

Standing-wave excitation of fluorescence in a laser-scanning microscope allows precise contour mapping of the red blood cell membrane
TL;DR: In this paper, the authors demonstrate fluorescence excitation at multiple planes in a laser-scanning microscope by using the standing wave from a mirror placed close to the specimen, with an axial resolution of ≈90 nm.

Electro-Mechanical to Digital Projection
TL;DR: The history of television's development is a voluminous one, spanning facsimile, electro-mechanical, all-electronic, and digital technology as discussed by the authors, and it has taken many decades and advances in technology to achieve performance comparable to photochemical-celluloid film motion picture projection.

Local dimming in multi-modulation displays
TL;DR: In this article, dual and multi-modulator projector display systems and techniques are disclosed, where a light source, a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs the image with a Point Spread Function (PSF); and a second modulator receiving the blurred image and rendered a pulse width modulated image which may be projected to form the desired screen image.
