Integral imaging is a type of multidimensional imaging technique that captures and displays three-dimensional scenes or objects. It involves capturing multiple perspectives of a scene using an array of small lenses or micro-lenslets, which are then combined to create a single 3D image that can be viewed from different angles without the need for special glasses or equipment. This technology is commonly used in applications such as medical imaging, virtual reality, and immersive displays. Integral imaging has the potential to significantly improve the realism and depth perception of images and videos compared to traditional 2D displays.
