Electron Ghost Imaging.

Area of Science:

• Physics
• Optics
• Imaging Science

Background:

• Traditional imaging techniques often require pixelated detectors, which can be limiting in certain experimental setups.
• Electron beam manipulation offers potential for advanced imaging capabilities.

Purpose of the Study:

• To demonstrate a novel electron ghost imaging technique.
• To show that this method can reconstruct images without a pixelated detector.
• To explore its advantages over conventional imaging methods.

Main Methods:

• Utilizing a digital micromirror device to modulate a photocathode drive laser.
• Controlling the transverse distribution of a relativistic electron beam.
• Correlating structured illumination patterns with total sample transmission.
• Employing a compressed sensing framework for image reconstruction.

Main Results:

• Successful demonstration of electron ghost imaging.
• Image retrieval achieved by correlating illumination patterns with transmission data.
• Compressed sensing improved reconstruction quality and reduced the number of required measurements.
