Systems and methods for passive multi-directional illumination in light-sheet fluorescence imaging and microscopy are disclosed herein. An elliptical light shaping diffuser is placed in the illumination path between the source of a light-sheet and the illuminated sample. The light-sheet is diffused anisotropically along two directions perpendicular to its propagation direction, eliminating stripe artifacts in obtained images. The method includes converting a light-sheet into an elliptically diffuse light-sheet by passing it through an elliptical light shaping diffuser, illuminating a sample with the elliptically diffuse light-sheet. The system includes a light-sheet source, an elliptical light shaping diffuser adapted to convert the light-sheet into an elliptically diffuse light-sheet to illuminate the sample, typical microscopy optics and lenses, and image capturing elements.
