Paper Abstract

A three-dimensional (3-D) imaging configuration with a holographic scanner and two auxiliary reflectors is discussed, which employs a Nd:YAG laser that operates at a wavelength of 1.06 μm. Compared with traditional scanners, holographic scanner has many advantages, such as smaller in size, lighter in weight and simpler in structure. The data collected are stored into a 3-D array of 8-bit intensity values and displayed in two ways, a 2-D intensity image or a 3-D image. The 3-D image is displayed on the screen of a computer according to the perspective transformation technology of coordinates.
