Holographic tomography applied to reconstruction of spatial distributions of refractive index: reconstruction quality and system parameters
The paper presents a new approach aimed for reconstruction of 3D distributions of refractive index based on the combined employment of holographic and tomographic methods. The numerical modeling is performed demonstrating the recording and reconstruction of a set of digital holograms registered at different angles to the object under study. 3D distributions of refractive index were reconstructed from the obtained distributions of phase variations. It is demonstrated that the reconstruction quality depends mainly on the number of recorded holograms, while their signal to noise ratios are of minor importance.
