Holograms are three-dimensional images created using laser light. They capture the light reflected from an object and record it on a special surface, allowing the image to appear as if it has depth. When viewed from different angles, holograms can show different perspectives of the object, making them unique compared to regular photographs. These images are often used in various fields, including art, security, and medicine. For example, holographic displays can enhance visual experiences in entertainment, while holograms on credit cards help prevent counterfeiting. Overall, holograms offer innovative ways to visualize information.
