Abstract: We are gifted with a pair of eyes and the ability to observe our surroundings in three-dimension.Reconstruction of spatial image has always been a great challenge.There have been many attempts to develop a simple and economic method to photograph a life-like image representing all three visual axes;the same way that the human eye perceives its surroundings.There are two basic techniques to produce a 3D image that does not require the use of special glasses:holography and micro-lenticule system.Due to the inherent technical limitations,holography has not yet become a practical imaging technique.The micro-lenticuls system,presumably is the most promising direction of future development of 3D photographic images.The history of lenticular 3D image can be traced back from the early 1940's when Baurice Bonnet,a French scientist,developed his first lenticular 3D photo in his studio in Paris.Then followed by the mass production of 3D lenticular lithographic prints during the 1950's & 1970's in the US and Japan.However,until today,lenticular 3D images have not yet been successfully developed as a consumer product due to its unstable image quality,complicated and unreliable processes.

Key words: 3-D image, lenticular screen, optics
