近几年来,全息术得到实际应用.自从1962年Leith和Upatnieks发表“双光束法”全息术具有实用价值的25年来,随着周围技术的发展,现在可以说客观评价全息术实用价值的时代已经到来.虽然,有“R＆D20年说”即一种技术应用到生产上需要20年的论调.但是,1980年3月使用全息扫描器的条型码读取装置(日本电气OBR—70—3型)这种全息术在实际工作中的应用,可以说世界上还尚属首次吧!
Holography has been practically used in recent years. Since the publication of the “double-beam method” holographic technique by Leith and Upatnieks in 1962, which has practical value, it is now time to objectively evaluate the usefulness of holography with the development of peripheral technology Although there is “R & D20 years”, that is, a technology to produce on the need for 20 years of argument.However, in March 1980 using a holographic scanner barcode reader (Japan’s electric OBR-70-3 type ) This holography in the practical application of work, it can be said for the first time in the world!
