From the queasy zooms in Alfred Hitchcock's Vertigo to the avant-garde mystery of Michael Snow's Wavelength, from the excitement of televised baseball to the drama of the political convention, the zoom shot is instantly recognizable and highly controversial. In The Zoom, Nick Hall traces the century-spanning history of the zoom lens in American film and television. From late 1920s silent features to the psychedelic experiments of the 1960s and beyond, the book describes how inventors battled to provide film and television studios with practical zoom lenses, and how cinematographers clashed over the right ways to use the new zooms. Hall demonstrates how the zoom brought life and energy to cinema decades before the zoom boom of the 1970s and reveals how the zoom continues to play a vital and often overlooked role in the production of contemporary film and television.

Imaging methods such as X-ray microscopy are used in non-destructive material analysis to achieve resolutions in the sub micrometer range. Imaging optics are required, for which X-ray lenses are particularly suitable for photon energies above 10 keV. To ensure the universal use of these lenses with constant optical properties over a wide photon energy range, for the first time an X-ray zoom lens was developed in this work.

Liquid Crystal on Silicon (LCoS) has become one of the most widespread technologies for spatial light modulation in optics and photonics applications. These reflective microdisplays are composed of a high-performance silicon complementary metal oxide semiconductor (CMOS) backplane, which controls the light-modulating properties of the liquid crystal layer. State-of-the-art LCoS microdisplays may exhibit a very small pixel pitch (below 4 ?m), a very large number of pixels (resolutions larger than 4K), and high fill factors (larger than 90%). They modulate illumination sources covering the UV, visible, and far IR. LCoS are used not only as displays but also as polarization, amplitude, and phase-only spatial light modulators, where they achieve full phase modulation. Due to their excellent modulating properties and high degree of flexibility, they are found in all sorts of spatial light modulation applications, such as in LCOS-based display systems for augmented and virtual reality, true holographic displays, digital holography, diffractive optical elements, superresolution optical systems, beam-steering devices, holographic optical traps, and quantum optical computing. In order to fulfil the requirements in this extensive range of applications, specific models and characterization techniques are proposed. These devices may exhibit a number of degradation effects such as interpixel cross-talk and fringing field, and time flicker, which may also depend on the analog or digital backplane of the corresponding LCoS device. The use of appropriate characterization and compensation techniques is then necessary.
