| 總結: | Improvements in instrumentation and image handling techniques mean the indirect reconstruction is now realising the promise it has long offered. This approach recovers the phase and modulus of the specimen exit plane wavefunction using datasets comprising either through focal or tiltazimuth series of images. In order to achieve this it is necessary to measure the objective lens aberrations to high accuracy. This paper will review progress in implementing this approach and will present recent reconstructions from a range of materials. |
