Extended Data Fig. 2: Projecting 2D images with holographic light sheets.

Four digits ‘1 2 3 4’ are projected in the lateral direction perpendicular to the display. The lateral separation between the images is (a) 3.042 mm, (b) 1.872 mm, (c) 0.936 mm, and (d) 0.468 mm. The horizontal and vertical scale bars are 10 mm and 0.5 mm, respectively. Here, cross-talk (signified by ϵ) can be reduced by placing the images further apart in the lateral direction without affecting the size of the projected images. Furthermore, given their non-diffracting behavior, our holographic light sheets exhibit a relatively smooth profile (with less grainy features) compared to Fresnel-based multi-plane techniques.
