However, traditional LSFM typically relies on single-sided illumination and the stripe artifacts due to partial obstruction or scattering of the illumination beam, resulting in the formation of shadow artifacts. Uneven illumination, particularly in non-transparent samples, results in poor contrast in certain regions of the image and reduces image uniformity. To address this problem in compact fashion, a metalens-based dual-sided illumination LSFM (MDI-LSFM) is presented, which utilizes twin light-sheets for uniform sample illumination.
