丹尼斯·盖伯于去年逝世,从而结束了他光辉的一生。他是一位才华出众的研究工作者,曾在许多不同的领域作出许多发明创造。他最出名的贡献当然是全息照相术,但在其它领域还有许多贡献,随着时间的推移,完全有可能看到其中某些贡献会象全息术一样重要。促使丹尼斯·盖伯发明全息照相术的因素是众所周知的。然而,假定我们要十分了解全息术,那么除了盖伯是如何作出这一独创性发明的历史知识外,我们还得思考全息照相术是如何发生的。我认为大致有六条途 Dennis Gable died last year, ending his glorious life. He is a talented researcher who has made many inventions in many different fields. His most famous contribution is, of course, holography, but there are many other contributions that make it entirely possible over the course of time to see some of these contributions as important as holography. The factors that prompted Denis Geber to invent holography were well known. However, given that we have a good understanding of holography, in addition to the historical knowledge of how Gai Bo made this original invention, we have to think about how holography takes place. I think there are roughly six ways
