    Abstract: A tilted structured illumination pattern for use in an optical system is generated, wherein the tilted structured illumination pattern is not symmetrical about a center point of a back pupil of the system, and wherein the tilted structured illumination pattern is based on exactly two wave vectors and defines spatial frequencies along an optical axis of an objective of the system. The tilted structured illumination pattern is directed to be incident on a sample, such that one or more fluorophores of the sample are excited by the structured illumination pattern. A phase of the tilted structured illumination pattern is varied. A set of images of fluorescence emission emitted by the sample is captured, wherein each image of the set of images corresponds to a respective phase of the tilted structured illumination pattern and to a respective axial imaging plane. Combined image data is generated based on the set of images.
