holographic techniques

Holographic techniques involve creating three-dimensional images by recording and reconstructing light patterns. A hologram captures both the intensity and phase of light waves reflected from an object, encoding depth and details. When illuminated with a suitable light source, the hologram reconstructs the original light wavefronts, producing a lifelike 3D image that can be viewed from different angles. These methods are used in security, data storage, medical imaging, and art, enabling realistic, detailed visuals without needing special glasses, and often involve laser technology and precise interference measurements to achieve high-resolution 3D representations.
