MICROWAVE-ASSISTED MOIRÉ DEFLECTOMETRY

摘要

An apparatus includes: (1) a series of gratings configured to block ballistic trajectories through the gratings; (2) an analyte gas source positioned upstream of the gratings, and configured to emit a beam of gas phase molecules; (3) a deflection field generator configured to apply a deflection field in a region of the gratings, the deflection field configured to selectively deflect a subset of the molecules to allow their transmission through the gratings; and (4) a detector positioned downstream of the gratings, and configured to detect transmitted molecules.
