Paper Abstract

The spherical fiber optic diffuser is for producing a spherical scattering light field. A uniform light intensity distribution is the most desired pattern for many medical applications. This paper presents a theoretical model for describing the surface irradiance and the far-field intensity distribution, which are expressed as a function of scattering coefficient, radius of the diffuser, and the maximum semi-angle of the output beam from fiber end. Experimental results are given and compared with the theoretical model.
