Difference between Holography and Photography
Holography and photography are two different techniques to generate images.
It is the technique used to generate 3-dimensional images using the phenomenon of Interference and diffraction of light. It uses monochromatic and coherent source of light and a hologram is needed to regenerate the image.
It is the technique used to generate 2-dimensional images of an 3-dimensional object. In this light reflect from the object strike on the photographic film and react with the chemical coating of the film. A lens is needed to focus the object on the photographic plate.
Difference between Holography and Photography:
|1.||Holography is used to generate 3-dimensional images.||Photography is used to generate 2-dimensional images.|
|2.||Phenomenon used in holography is interference and diffraction of light.||It uses reflection of light by the object to the photographic film.|
|3.||Source of light should be monochromatic and coherent.||No special type of light source is needed.|
|4.||No lens are required to generate the holograph.||Lens are required to focus on the object and generate the photograph.|
|5.||Holography has high information capacity.||Photography has less information capacity than holography.|
|6.||Multiple images can be superimposed together.||Multiple images can’t be superimposed together.|
