Tupac returns in Hologram. The late Tupac Shakur made a surprise return on stage at the Coachella festival, in hologram form.
A hologram requires a laser as the sole light source. Lasers can be precisely controlled and have a fixed wavelength.
Holography is a technique that enables a light field which is scattered off of objects, to be recorded and later reconstructed so that an image of the object will be seen even when the object is no longer present.
