Investigations to the digital holography with the locally fanned up continuous spectrum obtained from an ultrashort pulses (KR 953/25-1)
Within the scope of the project the fundamentals for the detection of digital holograms with spatially fanned up wavelengths should be created under use of ultrashort light pulses to develop a new metrology to investigate wavelength dependent phenomena. Here, all wavelengths of the continuous spectrum should be used at the same time in a short-term exposure. The detection used the spectrally fanned reference beam to record the wave field with different wavelength along small parallel stripes over the digital hologram. A theoretical description of this effect should be delivered and an algorithm for reconstruction of complex wave fields from such holograms has to be developed.
