We introduce a color imaging method in our digital holographic\udmicroscope system (DHM). This DHM can create color images of freely\udfloating, or moving objects inside a large volume by simultaneously\udcapturing three holograms using three different illumination wavelengths. In\udthis DHM a new light source assembly is applied, where we use single\udmode fibers according to the corresponding wavelengths that are tightly and\udrandomly arranged into a small array in a single FC/PC connector. This\uddesign has significant advantages over the earlier approaches, where all the\udused illuminations are coupled in the same fiber. It avoids the coupling\udlosses and provides a cost effective, compact solution for multicolor\udcoherent illumination. We explain how to determine and correct the\uddifferent fiber end positions caused tilt aberration during the hologram\udreconstruction process. To demonstrate the performance of the device, color\udhologram reconstructions are presented that can achieve at least 1 μm lateral\udresolution.
