Optimal spatial bandwidth capacity in multiplexed off-axis holography for rapid quantitative phase reconstruction and visualization

We present new methods for optimizing the spatial bandwidth capacity in off-axis holography using spatial multiplexing. We use optimal spatial multiplexing of off-axis holograms to fill the entire spatial frequency domain, including the space previously occupied by the intensity of the sample. Our approach enables spatial digital compression of eight offaxis holograms into a single real-valued ...

Real Time Temperature Distribution Measurement of a Microheater by Using Off-Axis Digital Holography

Off-axis setup taking full advantage of incoherent illumination in coherence-controlled holographic microscope.

Coherence-controlled holographic microscope (CCHM) combines off-axis holography and an achromatic grating interferometer allowing for the use of light sources of arbitrary degree of temporal and spatial coherence. This results in coherence gating and strong suppression of coherent noise and parasitic interferences enabling CCHM to reach high phase measurement accuracy and imaging quality. The a...

Field Mapping in Semiconductors by Off-axis Electron Holography: From Devices to Graphene and Single Dopant Atoms

Off-axis electron holography is an electron microscopy-based technique that allows the electrostatic and magnetic fields in and around a specimen to be measured with nm-scale resolution. The continuous reduction in the size of semiconductor devices means that information about the distribution of strain fields and active dopants at a nanometre scale is required in order to understand how these ...
