The patent covers an innovative device based on a high frequency shuttered grating.
The device gates the transit time of the incoming particles flux into the device. The shutter motion allows to precisely track the particles entry time without altering their energy and direction. Thanks to that it is possible to reconstruct the particles velocity distribution.
When the device is coupled to a pixellated focal plane assembly, the system may be also used as an advanced atomic camera such as the AMDL one on-board BepiColombo ESA Mission.
