### Phaseless Near-Field Optical Tomography

Alexander Govyadinov, George Panasyuk, John C. Schotland

The model (left panel) and the simulated reconstruction (right panel) of a set of point-like scatterers with complex valued susceptibilities arranged in two planes at z = 0.068 λ (top row) and z = 0.018 λ (bottom row). The sample is sequentially illuminated with two scalar plane waves from the lower half-space of refractive index 1.5. The angle of incidence is such that waves are evanescent in the upper half-space. The extinguished power is measured for a set of probe positions above the sample. Values on x and y axes are in micrometers. The susceptibility is normalized to the maximum of each image.
