Abstract: 2D Image reconstructions of some phantoms have been obtained from a portable design of a transversal optical computed tomography (OCT) scan. A laser diode of an NIR (Near-Infrared) peak spectrum at 904 nm has been used as a light source through a standard technique of scanning. The phantoms used for the experiments were of cylinders of gypsum and stainless steel materials. This technique is considerably encouraging for further applications that could introduce some advantages of simply operation and low cost.


Keywords: optical tomography, phantom, NIR, gypsum, stainless steel
