In widefield fluorescence microscopy, images from all but very flat samples suffer from fluorescence emission from layers above or below the focal plane of the objective lens. Structured illumination microscopy provides an elegant approach to eliminate this unwanted image contribution. To this end a line grid is projected onto the sample and phase images are taken at different positions of the line grid. Using suitable algorithms 'quasi-confocal images' can be derived from a given number of such phase-images. Here, we present an alternative structured illumination microscopy approach, which employs two-dimensional patterns instead of a one-dimensional one. While in one-dimensional structured illumination microscopy the patterns are shifted orthogonally to the pattern orientation, in our two-dimensional approach it is shifted at a single, pattern-dependent angle, yet it already achieves an isotropic power spectral density with this unidirectional shift, which otherwise would require a combination of pattern-shift and -rotation. Moreover, our two-dimensional approach also yields a better signal-to-noise ratio in the evaluated image.

The Journal of Microscopy is the oldest journal dedicated to the science of microscopy and is the only peer-reviewed publication of the Royal Microscopical Society. It publishes papers reporting the latest developments in microscopy techniques, including advancements in microscopy technology and new areas of application. While the journal does not seek to publish routine applications of microscopy or specimen preparation, submissions with high scientific value will be considered. The scope encompasses research in both physical and biological sciences, covering imaging methods using light, electron, X-ray, and other radiation techniques, as well as atomic force and near-field techniques. Interdisciplinary research is also welcomed. Papers related to microscopy, particularly those involving optical theory, spectroscopy, new specimen preparation and operational methods, as well as image recording, processing, and analysis (including dynamic analysis of live specimens), are highly encouraged. Publication types include full articles, rapid communications on hot topics, and review articles. Authors considering submitting review articles should first contact the editorial office.
