Pulsed electron holography

Proposal for a High-brightness Pulsed Electron Source*

We propose a novel scheme for a high-brightness pulsed electron source, which has the potential for many useful applications in electron microscopy, inverse photo-emission, low energy electron scattering experiments, and electron holography. The source makes use of Cs atoms in an atomic beam. Each cycle of the device begins with a laser pulse that excites a single Cs atom on average to a band o...

Manufacturing of Surface Relief Structures in Moving Substrates Using Photoembossing and Pulsed- Interference Holography

Photoembossing is a cost-effective technique for the production of complex surface relief structures in a photopolymer film, achieved via contact-mask exposure to UVlight. Here, photoembossing is explored using interference holography with a CWlaser and a nanosecond pulsed laser. It is shown that identical surface relief structures are produced if the photopolymer film is kept in a fixed positi...

Pulsed Full-Color Digital Holography with a Raman Shifter

Holography deals with processes involving the transformation of waves by interference structures that are formed when coherent electromagnetic waves interact with matter (Andreeva, 2002). As an optical technique it was introduced in the seminal works of Gabor, Leith, Denisyuk and others in the 1960’s (Benton, 2005). By succeeding to reconstruct the complete wave (full amplitude and phase inform...

Terahertz pulsed time-domain holography and iterative phase retrieval methods

We present latest results obtained in the scope of imaging methods which allows one to recover spatial phase distribution in the terahertz wave-fields. One of these methods is the terahertz pulse time-domain holography. The second one is the iterative phase retrieval approach, transferred from the visible frequency range.
