We employ the pseudospectral time-domain (PSTD) algorithm to model light propagation through a macroscopic scattering medium. We show that with specific amplitude and phase, light can propagate through scattering media and focus. We model explore the feasibility to propagate light the scattering medium with imprecise amplitude or phase. Based upon the numerical experiment, we analyze the degradation due to such imprecision.
Both consist of collagen fibrils, sclera is opaque whereas cornea is transparent for optical wavelengths. By employing the pseudospectral time-domain (PSTD) simulation technique, we model light impinging upon cornea and sclera, respectively. To analyze the scattering characteristics of light, the cornea and sclera are modeled by different sizes and arrangements of the non-absorbing collagen fibrils. Various factors are analyzed, including the wavelength of incident light, the thickness of the scattering media, position of the collagen fibrils, size distribution of the fibrils.
