Holography with a neutron interferometer
(The Optical Society, 2016-10-03)We use a Mach-Zehnder interferometer to perform neutron holography of a spiral phase plate. The object beam passes through a spiral phase plate, acquiring the phase twist characteristic of orbital angular momentum states. ...
