Figure 17.8
Schematic representation of the optical system leading to the formation of lens hologram: (1)
Prismatic nano-object of dielectric material; (2) wavefronts entering and emerging from the
polystyrene microsphere acting as a relay lens; (3) wavefronts arriving at the focal plane of
the spherical lens; (4) wavefronts arriving at the image plane of the CCD. The simulation of the
overlapping of orders 0, 1, and 1 in the image plane of the CCD is also shown [10] .
