It has been reported that the use of illumination with sinusoidal intensity pattern is efficient in noncontact optical tomography. Although this imaging method of using spatial frequency is promising, most research so far has relied on the diffusion approximation to the radiative transport equation. Here, a numerical algorithm of optical tomography with spatially sinusoidal illumination for the radiative transport equation are proposed. With the help of the technique of rotated reference frames, the forward problem, i.e., the three-dimensional radiative transport equation is solved by the three-dimensional FN method. Then the inverse problem is solved by making use of the Green’s function, which is the solution to the forward problem.
