Digital Interference Holography: Development of a New Tomographic Microscopy Instrument

南佛罗里达大学的Myung Kim博士获得了一笔拨款，以进一步开发一种用于显微光学切片和层析成像的新型仪器。该仪器是基于最近介绍的波长扫描数字干涉全息（DIH）原理。本项目为期三年的研究目标是：(1)研制出符合实际显微成像应用的关键参数原型仪器；（二）建立图片库，以便将成像方法和仪器应用于广泛的标本；(3)开发相关生物医学应用和新技术。一个重要的长期目标是开发一个紧凑、多功能和经济的成像系统，这将有助于进一步扩大应用范围。随着其能力的充分发展，数字干涉全息术提供了一种简单而通用的获取和操作微观物体三维数字模型的模式，有可能影响光学显微镜和断层扫描的一般领域。

A grant has been awarded to Dr. Myung Kim at the University of South Florida to further develop a novel instrument for microscopic optical sectioning and tomographic imaging. The instrument is based on the recently introduced principle of wavelength scanning digital interference holography (DIH). The proposed three-year research program aims to: (1) develop a prototype instrument with key parameters consistent with practical microscopic imaging applications; (2) build up an image gallery for the purpose of applying the imaging methods and the instrument to a wide range of specimens; and (3) develop relevant biomedical applications and new techniques. One of the important long-term goals is to develop a compact, versatile, and economical imaging system, which will help further widen the range of applications. With full development of its capabilities, digital interference holography has the potential to impact the general field of optical microscopy and tomography by providing a simple and versatile mode of acquiring and manipulating three-dimensional digital model of microscopic objects.
