AI Article Synopsis
- The study presents a new method called multimode ptychography, which improves imaging techniques by using partially coherent light.
- It demonstrates that you can reconstruct images uniquely by scanning the sample and recording enough diffraction patterns based on the light's modes.
- The findings reveal that this method can accurately analyze samples, making it a significant advancement in analytic imaging methods.
Article Abstract
By writing diffracted intensities as a set of linear equations with the self-correlation of sample's Fourier components as unknown terms and the self-correlation of illumination's Fourier components as coefficients, it was found that the number of unknown terms to be determined is much larger in partially coherent PIE than that in purely coherent PIE. When a partially coherent illumination composed of N modes was applied a unique reconstruction can be determined by scanning the sample to at least 4N positions and recording 4N frames of diffraction patterns. While mathematically illustrating the physical mechanism of multimode ptychography and numerically demonstrating its capability in generating unique reconstruction under partially coherent illumination, this study showed for the first time that multimode ptychography could be an analytic imaging method.
