romantic education:reading william wordsworths the prelude in the light of the history of ideas
عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
Wave-Optical Computing Based on White-Light Interferometry
The basic idea of the method [1] is best demonstrated with a simple problem that already is given in terms of paths. Fig. 1 depicts how we can solve a typical maze problem. The maze is equipped with mirrors so that light entering the maze simultaneously runs through all possible paths. Interference will be detected if the optical path lengths (OPD) of the two interferometer arms are equal. Ther...
متن کاملOptical high voltage measurement transformer using white light interferometry
A new approach to perform measurement of potentials in high voltage levels using electrooptical Pockels sensors is presented here. This paper describes an application of the White Light Interferometry technique to a high voltage optical fiber measurement system. In this system the information is encoded in the spectrum of the light, allowing the measurement to be independent of the optical powe...
متن کاملBasics of White-Light Interferometry
Interferometer Setup The Twyman–Green interferometer (Figure 1) is a special configuration of the well-known Michelson interferometer with optics that superimpose the images of the object and the reference planes. Polytec engineers use this interferometer and place a CCD image sensor like those used for digital photography at the point where the two images are superimposed. A broadband “white-l...
متن کاملMoiré interferometry with white light.
While high-sensitivity moiré interferometry requires monochromatic light, an auxiliary compensator grating removes the requirement. Experimental verification utilized white light for moiré interference of sensitivity 0.833 microm/fringe. Configurations readily amenable to compensation include moiré fringe multiplication by even factors and the minimum-deviation arrangement. Chromatic compensati...
