Neutron interferometry using a single modulated phase grating

Phase Tomography in Neutron Interferometry

Perfect crystal neutron interferometry permits the simultaneous investigation of different interactions, like absorption, small angle scattering, and forward scattering. The coherent forward scattering of neutrons in materials or magnetic fields generates phase shifts, which can be detected with high sensitivity. The tomographic reconstruction of phase projections is similar to that of intensit...

A Novel Stand-Alone Single-Phase Induction Generator Using a Three-Phase Machine and a Single-Phase PWM Inverter

A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...

N-Shots 2N-Phase-Steps Binary Grating Interferometry

Two-wavelength double heterodyne interferometry using a matched grating technique.

Two-wavelength double heterodyne interferometry is applied for topographic measurements on optically rough target surfaces. A two-wavelength He-Ne laser and a matched grating technique are used to improve system stability and to simplify heterodyne frequency generation.

Spatial Non-Cyclic Geometric Phase in Neutron Interferometry

We present a split-beam neutron interferometric experiment to test the non-cyclic geometric phase tied to the spatial evolution of the system: the subjacent two-dimensional Hilbert space is spanned by the two possible paths in the interferometer and the evolution of the state is controlled by phase shifters and absorbers. A related experiment was reported previously by some of the authors to ve...
