Paper Abstract

The potentialities are investigated of a single-sided optical tomography approach based on lidar principle. Concretely, the informative depth of sensing is estimated that outlines the underside area in the probed object where one could reveal inhomogeneities with some desirable contrast. The sensing radiation is supposed to consist of picosecond laser pulses with pulse repetition rate of ~ 10 MHz and optimum wavelength of 800 nm. The maximum permissible skin exposure is considered as determinant. The longitudinal and the transversal resolution intervals are chosen to be 2 mm and 3 mm (or 1 cm), respectively. It is shown that, under the above described conditions, inhomogeneities with contrast 1-10 % would be detected at depths of 1 to 4 cm, depending mainly on the values of the attenuation coefficient chosen here to vary correspondingly from 1.4 mm-1 to 0.4 mm-1.
