Abstract

Optical absorption tomography is used to map the iodine-vapor density in a plane. Two-dimensional images are obtained with 1-cm spatial resolution by using a fan-beam geometry with a 56-cm-diameter source circle. Experimental results confirm a theoretical analysis of noise in the reconstructed image, including the effects of correlated noise, position within the image, and spatial averaging.
