Summary:
In medical image diagnosis using optical waves of laser, image responses of optical transmitted projection include optical scattering characteristics that disturb transmission properties through biological structures depending on optical absorption effects. We have studied spatial filtering by lossy grid array for optical scattering superposed on transmitted and attenuated waves to improve image diagnosis. In this paper, reflection and transmission characteristics of waveguide-type spatial filter are studied by FDTD method, comparing with approximate analytical method for optimum design of spatial filter.
