Holography with Non-coherent Light
A new technique of making holograms with non-coherent light has been demonstrated using continuousspectrum white light zirconium arc source. Such a technique, employing diffraction gratings as beam splitters and beam deflectors, allows easy control of the modulation transfer function so as to produce low-pas s . band-pass or high-pass characteristics by simply changing the position of either on...
متن کاملPhotoacoustics with coherent light.
Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established. In particular, light propagation in photoacoustic imaging is generally considered from the perspective of transport theory. However, recent breakthroughs in optics have shown that ...
متن کاملWhen holography meets coherent diffraction imaging.
The phase problem is inherent to crystallographic, astronomical and optical imaging where only the intensity of the scattered signal is detected and the phase information is lost and must somehow be recovered to reconstruct the object's structure. Modern imaging techniques at the molecular scale rely on utilizing novel coherent light sources like X-ray free electron lasers for the ultimate goal...
متن کاملGeneralised Holography Meets Coherent Diffractive Imaging
Coherent diffractive imaging (CDI) is an imaging technique that seeks to restore the exit-surface wave from intensity measurements, either in the far field diffraction plane or the Fresnel diffraction region. To date numerous strategies have been proposed to complete this restoration, the most successful being the original scheme proposed by Gerchberg and Saxton and its subsequent modifications...
