We present a new approach to optical tomography of phase objects that is referred to as differential interference contrast tomography (DICT). The main feature of DICT is that the result of tomographic reconstruction is a 3D DIC image. This image is described by partial derivative of 3D refractive index distribution in one direction. The DICT setup consists(More)
A new approach to the problem of measuring the phase shift from variances of interferogram differences based on Fourier domain analysis is proposed. It is shown that the use of true variance of the interferogram differences and spatial apodization of interferograms increases the accuracy of the phase shift of the measurement. Numerical simulations and(More)
