Abstract
A reconstruction theory for intensity diffraction tomography (I-DT) has been proposed that permits for the reconstruction of a weakly-scattering object without explicit knowledge of phase information. In this work, we examine the noise properties of I-DT. An explicit expression for the variance of the estimated object function as a function of spatial frequency is derived and employed for understanding the noise properties of images reconstruction in I-DT. It is demonstrated analytically and numerically that the noise properties of I-DT are significantly different from those of conventional diffraction tomography (DT).
