holography Definition

ho·log·ra·phy (hō läg′rə fē)

noun

a method of making three-dimensional photographs without a camera, by splitting a laser beam into two beams and recording on a photographic plate the minute interference patterns made by one beam going from the laser to the plate and the other beam going from the laser to the object to the plate: the virtual image can be reconstructed by shining laser light, white light, etc. through the developed film

Etymology: holo- + -graphy
