基于数字全息术的水中气泡场获取方法的研究

水中气泡场是海洋和大气热交换的重要媒介,随着对海洋研究的深入,水中气泡场的研究越来越受到人们的重视。数字全息术由于具有可获取三维空间信息、可进行实时实地测量、不干扰被测对象等优点,所以可成为获取水中气泡场的有效手段。研究了数字全息技术在水中气泡场探测中的应用,并进行了数字全息拍摄的实验和再现,探讨了获取水中环境对获取气泡场的影响,讨论了实验中出现的问题,并对所得到的再现图像数据进行了分析和讨论。

The research of under water bubble field on digital holography

The underwater bubbles field is an major media on heat exchange between marine and atmosphere. With the research of marine,people pays more and more attention to the underwater bubbles fields. The digital holography technology has the advantages of quasi-real-time detection to facilitate operations at sea,so it is made one of the most important means in access to the underwater bubbles field. The application of the digital holography technology in underwater bubbles field detection is researched. The influences of underwater environments on bubbles field detection are investigated. The problems in experiment are discussed. The obtained numerical representation data are analyzed.
