Holographic microscopy is a technique that combines holography and microscopy to create detailed three-dimensional images of microscopic objects. Holography captures both the intensity and phase information of light waves, allowing for the reconstruction of full three-dimensional images of objects. This technique is used in various fields such as biology, medicine, and materials science to study the structure and dynamics of microscopic samples with high resolution and detail. Holographic microscopy offers advantages over traditional microscopy techniques, including label-free imaging, quantitative phase imaging, and the ability to capture dynamic processes in real-time.
