Three-dimensional (3D) moment imaging with a USB3 oscilloscope.

We report a new implementation of a recently developed 3D momentum imaging technique [Lee et al. J. Chem.

Slicing Newton spheres with a two-camera 3D imaging system.

We demonstrate a simple approach to achieve three-dimensional ion momentum imaging. The method employs two complementary metal-oxide-semiconductor cameras in addition to a standard microchannel plates/phosphor screen imaging detector. The two cameras are timed to measure the decay of luminescence excited by ion hits to extract the time of flight.
