光栅立体影像的技术进展

人类处于三维世界之中.用我们一双明亮的眼睛能够辨别周围物体所处的相对空间位置,感受这美妙的立体世界.但是,至今广泛采用的照相术,只能记录平面影像,缺乏真实感.立体影像是继平面影像的自然演进.大约30年前,东京大学教授大越孝敬在他1976年的著作《三次元画像工学》里提到"重建空间影像是人类的梦想".其实,这个梦想早已开始,F.E.Ives于1903年已发表利用光栅的立体影像原理.光栅立体影像的应用发展始于1940年,至今已有60多年历史,但一直都未能普及化,一定有其中的原因.

HISTORY OF DEVELOPMENT OF MICRO-LENTICULE 3-D IMAGING TECHNOLOGY

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.
