Beam-deflection optical tomography of the refractive-index distribution based on the Rytov approximation.
A method of beam-deflection optical tomography based on the Rytov approximation of the wave equation is proposed. A linear relation between the deflection angle and the refractive-index distribution from the Rytov approximation and an equation of geometrical optics is derived. The tomographic reconstruction in this method is reduced to the solution of a system of linear equations. Experimental results show that this method can reconstruct strongly refracting fields from projection data of six view angles.
