High-resolution tomographic diffractive microscopy of biological samples

J Biophotonics. 2010 Jul;3(7):462-7. doi: 10.1002/jbio.200900094.

Abstract

The authors have developed a tomographic diffractive microscope that combines microholography with illumination from an angular synthetic aperture. It images specimens relative to their complex index of refraction distribution (index and absorption) and permits imaging of unlabelled specimens, with high lateral resolution. The authors now study its use for biological applications, and imaged several preparations with fluorescence confocal microscopy and tomographic diffractive microscopy. The results highlight some interesting features of this instrument, which should attract the interest of biologists for this new technique.
