一、立体图像的概念: 在扫描电镜下观察到的二次电子图像,能显示样品表面的形貌,由于其焦深较大,并根据图像中某些结构遮档显示的阴影,使人们有立体感的印象。但这不是真正的立体图像,也不具有第三维的信息,只是一张二维图象。立体图像一定要具有人们双眼立体视觉的效果,要有第三维的信息。左右两眼看物体时由于观察角度不同所造成 First, the concept of three-dimensional images: The second electron image observed under a scanning electron microscope, can display the surface morphology of the sample, due to its larger focal depth, and according to some of the structures in the image shade shows that people have Three-dimensional impression. However, this is not a true stereoscopic image nor a third-dimensional information, but a two-dimensional image. Stereoscopic images must have the effect of binocular stereoscopic vision of people, to have the third dimension of information.
