Incoherent image
WebZ-contrast images are formed by mapping the intensity of high-angle scattered electrons as the electron probe is scanned across the specimen. Z-contrast images are incoherent, have double the resolution of coherent images, and do not reverse contrast with focus or specimen thickness.

WebAug 20, 2024 · There are significant recent interests in using nanophotonic structures to perform computations in the optical domain. Specifically in optical image processing, there have been a number of demonstrations using nanophotonic structures to perform edge detection and spatial filtering operations on images without the bulky 4f systems. These …
Webdigital incoherent image processing system is consid-ered in which a TV camera device coupled with an annular aperture is used. Isolated zeros in the OTF of a defocused system are avoided by choosing an annular aperture with a proper radius ratio. The loss of image contrast is restored by using a computer-generated annular-pass filter. WebHere, we present a new concept, image-guided wavefront shaping, allowing widefield noninvasive, guidestar-free, incoherent imaging through highly scattering layers, without illumination control. The wavefront correction is found even for objects that are larger than the memory-effect range, by blindly optimizing image quality metrics.
