rden sollte, im Unterricht würde ausschließlich Wissen vermittelt, das der Erwachsene später auch benötige. So unzutreffend (und legitimatorisch) die Formel ist, was die Unterrichtsinhalte selbst angeht, so hat sie doch einen wahren Kern, der sich auf die Schule als sozialen Erfahrungsraum bezieht N

Introduction,the early 1950s. That volume covers a diverse array of topics, involving spectroscopy, applications, and technologies of the submillimeter region of the spectrum, and as such provides a useful snapshot of the state of the art in 1970. In some ways, the sentiments expressed in the above quotation rem

Terahertz Imaging,tion and detection of far-IR light have been proposed and demonstrated, many of which have relied on nonlinear optical techniques. Although the use of nonlinear optics for far-infrared generation was proposed as early as 1976 , widespread application has been hindered until recently by the limite

Free-Space Electro-Optic Techniques,cy range presents the next frontier in imaging science and technology. Compared to the relatively well-developed imaging techniques at microwave and optical frequencies, however, basic research, new initiatives, and advanced technology developments in the terahertz band are very limited. The “THz ga

Photomixers for Continuous-Wave Terahertz Radiation,ilms of low-temperature-grown (LTG) GaAs. Optimizing photomixers for maximum output power requires careful design of the epitaxial growth sequence, and detailed analyses of the RF circuitry and of the optical feed. Control of the LTG GaAs epitaxy leads to a material with short photocarrier lifetime

Bio-medical Applications of THz Imaging,mpete with established techniques, we start with a comparative discussion of modern imaging systems followed by a brief description of a THz imaging setup. We then give three examples in the life sciences where THz imaging is potentially useful. First, we describe an examination of wood density vari
