  We represent three-dimensional Fourier transform light scattering, a method
to reconstruct angle-resolved light scattering (ARLS) with extended angle-range
from individual spherical objects. To overcome the angle limitation determined
by the physical numerical aperture of an optical system, the optical light
fields scattered from a sample are measured with various illumination angles,
and then synthesized onto the Ewald Sphere corresponding to the normal
illumination in Fourier space by rotating the scattered light signals. The
method extends the angle range of the ARLS spectra beyond 90 degree, beyond the
limit of forward optical measurements. Extended scattered light fields in 3D
and corresponding ARLS spectra of individual microscopic polystyrene beads, and
protein droplets are represented.
