Imaging of particles using optical tomography based on charge-coupled device linear image sensor
The word ‘tomography’ is derived from two Greek words - ‘tomos’ and ‘graphia’. The word “tomos’ means slice while the word ‘graphia’ refers to image. Therefore, tomography is defined as developing cross-sectional images in order to visualize a process. The cross-section of this type is called tom...

Summary: | The word ‘tomography’ is derived from two Greek words - ‘tomos’ and ‘graphia’. The word “tomos’ means slice while the word ‘graphia’ refers to image. Therefore, tomography is defined as developing cross-sectional images in order to visualize a process. The cross-section of this type is called tomogram and the equipment that generates the image is a tomography (Hjertaker, 1994). The concept of tomography was first published as early as 1826 for an object with axi-symmetrical geometry, by a Norwegian physicist named Abel. In 1917, an Australian mathematician, Radon, extended Abel’s idea for objects with arbitrary shapes. |
