Article Synopsis
- This study focuses on advancing the understanding of phase contrast images taken with a hole-free phase plate in transmission electron microscopy (TEM).
- The researchers used a sinusoidal phase grating to analyze how the phase plate influences phase shift and image contrast by comparing experimental data to simulations.
- Key findings include the confirmation that image contrast originates from phase differences, the observation of contrast reversal and frequency doubling over time, and the lateral displacement of image fringes due to side beam phase differences.
