Digital Interference Holography: Development of a New Tomographic Microscopy Instrument

We have a program of research sponsored by the National Science Foundation to develop a novel instrument of optical sectioning or tomographic imaging. The instrument is based on the recently introduced principle of wavelength scanning digital interference holography (DIH). The images are reconstructed from a number of holograms digitally recorded while the wavelengths are varied at regular intervals, and the numerical interference of the multiple three-dimensional hologram fields results in tomographic images with narrow axial resolution. The proposed instrument has no mechanical moving parts. The image acquisition consists of N exposures of two-dimensional images, instead of pixel-by-pixel build-up of 3D volume. The range of physical sizes and resolution of objects that can be imaged is readily controlled by proper choice of the wavelength intervals. And with the holographic phase information readily available, further interferometric or holographic image processing is possible. The 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, the digital interference holography has a 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.
