Abstract
Recent advances in Digital Holographic Microscopy have been discussed in this paper, besides throwing some light on the designing aspects of optical components like beam splitter and neutral density filter for the optimization of system performance. Some important related subtopics like spectral resolution of digital holograms, and Fourier-synthesis holography have been technically discussed. The optimization of acoustical holographic components for use in renewable energy production is presented in this study. The production of solar energy can be increased via holograms. It has been mentioned that the University of Michigan researchers in Arizona recently created a novel method for harnessing the excess solar energy utilized to light a solar panel. To achieve the most efficient light collecting, the holographic light collector’s optical element must be symmetrically positioned in the middle of the photovoltaic module. There has also been a qualitative analysis of some significant research on the subject, particularly in the fields of biology and medicine. It is anticipated that the work will be beneficial to digital holographic microscopy researchers and designers. Furthermore, the study emphasizes the interdisciplinary nature of holography, showing its potential not only in optical instrumentation but also in advanced biomedical imaging, tissue engineering, and drug monitoring. By improving image reconstruction algorithms and enhancing hardware design, digital holography could revolutionize non-invasive diagnostics and provide real-time cellular monitoring. Future research directions may focus on integrating artificial intelligence and machine learning for automated hologram interpretation, which can significantly reduce human error and increase system efficiency.
Keywords: Digital holographic microscopy, spectral resolution of digital holograms, single element reflective digital holographic microscopy, and fourier-synthesis holography
