Experimental examination of the quantitative imaging properties of optical diffraction tomography

Optical tomography for dielectric profiling in processing electronic materials

“…Starting from the knowledge of E s at different wavelengths and/or different directions of incident field, several methods have been developed in order to invert equation (5) and reconstruct the function ( ) χ z [8][9].…”

“…Starting from the knowledge of the reflected field, both in amplitude and in phase, we could retrieve the doping profiles using the algorithms that have been developed to reconstruct dielectric profiles [8][9]. However, the phase measurements, at optical wavelength, require methods that are quite complicate from an experimental point of view.…”

Non-interferometric methods of phase estimation for application in optical tomography

“…For intensities measured on two arbitrary planes where the fields are not related through Fourier transform, Missell [12] proposed an iterative technique to get back the phase. This iterative method has been adapted for wavefront estimation for optical tomography by Maleki and Devany [13] and Wedberg and Stamnes [14]. There is also other reported work on data gathering for optical tomography where instead of path delay, a related quantity, beam deflection, is measured.…”

“…9, we can find the diffracted field in a similar manner as in section 4.1. To that end we first consider the field from the complementary slit, which according to the Kirchhoff diffraction theory is given by ': (10) where the amplitude function g(x) and the phase function 1(x) are given by 9(x)=v/;;:LsR (11) f(x)= R5+Rd-, (12) with Rd and R5 being the distances between the integration point Q(x, 0) and the observation point P(xd, Zd) and the source point S(0, -z), respectively (Fig. 9), i.e.…”
