Paper Abstract
A tomography image of a transparent object has been developed. Through a tomography scanning procedure, an
artificial and a real sinogram of transparent materials were developed. The artificial sinogram was used to test the
concept of transmitted light tomography. The effect of reflection and refraction of light to the map of refractive index of
transparent object is shown. A defect or faulty in transparent-material may appear as a deviation on the real-refractiveindex
distribution. The real sinogram was developed using an object phantom made of glass and a tube of water. A set of
projections or photographs was taken using a digital CCD camera. The object is rotated at a certain step then
subsequently the picture of the object was captured. Then in similar manner, the next picture was captured until the scan
covered 360 deg. From such set of pictures, a certain sinogram representing a certain cross-sectional was developed.
Then, using a summation filtered back projection scheme, formally used in x-ray tomography, the cross-sectional of the
object was developed. The results showed that it is possible to develop a transmitted light tomography for faulty
detection as indicated by a change of refractive index in material.
