Lasers made true 3D holograms possible
The invention of the laser in 1960 revolutionized holography, enabling the creation of the first true three-dimensional images just two years later, transforming a theoretical concept into a practical technology.
While Dennis Gabor invented holography in 1947, his early attempts produced blurry, 2D-like images. The real breakthrough came in 1962 when Emmett Leith and Juris Upatnieks used the newly invented laser's coherent light to create the first lifelike, three-dimensional holograms. This transformed holography from a theoretical concept into a versatile technology. These 3D images capture light's phase, allowing viewers to see depth and parallax just like real objects. Interestingly, Yuri Denisyuk independently created the first reflection hologram in 1962, viewable without a laser.
