Fratz, M., Giel, D.M., Fischer, P.
A new form of digital polarization holography is demonstrated that permits both the amplitude and the phase of a diffracted beam to be independently controlled. This permits two independent intensity...
Carl, D., Fratz, M., Pfeifer, M., Giel, D.M., Höfler, H.
A fast auto calibration method for (lensless) multi-wavelength digital holography with arbitrary temporal phase-shifts is presented. The calibration algorithm is simple to calculate and needs just...

Design and fabrication of polarization-holographic elements for laser beam shaping (2009)
Fratz, M., Sinzinger, S., Giel, D.
We report on an experimental realization of polarization-holographic optical elements (PHOEs) for laser beam shaping. The PHOEs were written into an azobenzene polymer layer by illumination with...
Fratz, M., Giel, D.M., Fischer, P.
We present polarization holograms with space-variant magnitude and orientation of the birefringence. They are fabricated in an Azobenzene thin-film and allow full control of the amplitude and phase...

Full phase and amplitude control in computer generated holography (2009)
Fratz, M., Fischer, P., Giel, D.M.
We report what we believe to be the first realization of a computer-generated complex-valued hologram recorded in a single film of photoactive polymer. Complex-valued holograms give rise to a...
