Paper Abstract

Multispectral quantitative phase imaging (QPI) with digital holographic microscopy (DHM) has been demonstrated to be a versatile tool to access wavelength dependent optical properties of technical and biological specimens as well as to reduce coherence induced image disturbances. However, when hyperspectral DHM is combined with microscopes and tunable lasers with a large spectral range, chromatic aberrations of the optical imaging system have to be considered. We have analyzed wavelength dependent defocusing effects and changes of the optical magnification in the related refocused holographic images in lens-based multi-wavelength DHM and show that both effects can be efficiently numerically compensated.
