Abstract

On comparison with the usual propagating scalar waves, the attenuation of diffuse photon density waves gives rise to important differences in structural information, such as higher spatial resolution in detection at short distances from objects and deviation from the Rayleigh limit at larger distances. This damping also establishes a minimum spatial resolution threshold for diffusive waves, which occurs by illumination in continuous mode, and demonstrates that in most cases spatial resolution is not improved by increasing the modulation frequency. Assessments of this formulation with numerical simulations of scattering and wave-front reconstruction in the presence of noise are given.
