What is the difference between photography and holography?
|1.The light from the object is scattered directly onto the recording medium in the recording of holography.||1.A lens is required in photography to record the image|
|2.A laser is required to record a hologram||2.A photograph can be recorded using normal light sources|
|3.In holography, both intensity as well as phase of light wave is recorded,thus holography gives 3-D picture of object.||3.In photography,only intensity is recorded so photography produces 2-D picture of the object.|
|4.There is a need of vibration less table for holography.||4.There is no need of vibration less table for photography.|
|5.When a hologram is cut in half, the whole scene can still be seen in each piece.||5.When a photograph is cut in half, each piece shows half of the scene.|
