Digital holography
Digital holography is a technique that captures and analyzes the light waves reflected from objects to create a three-dimensional image, called a hologram. Unlike traditional holography, which uses photographic films, digital holography employs digital sensors and computers to record and reconstruct these light patterns. This allows for high-resolution and detailed imaging, making it useful in fields like medicine for imaging tissues, in materials science for observing microstructures, and in metrology for precise measurements. The ability to manipulate and visualize data digitally enhances our understanding of complex shapes and structures in a variety of applications.

Digital holography is a sophisticated imaging technique that captures and reconstructs three-dimensional images of objects using light. It involves recording the light waves reflected off an object and combining them with a reference beam to create a hologram. This hologram is then processed with digital technology to produce a clear, detailed 3D image that can be analyzed. Unlike traditional photography, digital holography allows for precise measurements of the object's shape and surface, making it valuable in fields like materials science, biology, and medicine for studying structures at microscopic levels without physical contact.
