《大学物理引论(第2版)》：普通高等学校“十一五”国家级规划教材,双语多媒体教材

内容简介

恽瑛教授领导的课题组在物理教学方面从事研究工作已有近20年的历史。数年前，他们在多年教学研究实践的基础上创设了“双语物理导论”这一多学科集成的课程，以使大学低年级学生尽早具备阅读英文教材、物理文献的能力，培养这些同学能够早日参加课题研究的能力。这是一项非常有意义的工作。

插图：Holography is a technique for recording and reproducing an image of an object without the use of lenses. Unlike the two-dimensional images recorded by an ordinary photograph or a television system, a holographic image is truly three-dimensional. Such an image can be viewed from different directions to reveal different views, and from various distances to reveal changing perspective.The basic procedure for making a hologram is very simple in principle. A possible arrangement is shown in fig. 8-12a. We illuminate the object to be holographied with a monochromatic light, and we place a photographic film so that it is struck by scattered light from the object and also by direct light from the source. In practice, the source must be a laser, for reasons to be discussed later. Interference between the direct and scattered light leads to the formation and recording of a complex interference pattern on the film.To form the images, we simply project laser light through the developed film, as shown in fig. 8-12b. Two images are formed, a virtual image on the side of the film near the source, and a real image on the opposite side.
