Solution: SLAM is abbreviated for Simultaneous localization and mapping. It is a technique used by robots and autonomous vehicles to build a map within the unknown environment.

Solution: Holography enables a light field. It is to be recorded and later reconstructed when the original light field is no longer present.

Solution: A photograph can be captured using a normal light source. A laser is required to record a hologram.
