a) Fluorescence uniformity for the projection of an array of points onto a thick fluorescent slide under the different experimental conditions. ***, p < 0.001; ns, non-significant, p > 0.05, one-way ANOVA, Bonferroni post hoc test (N = 11).The GRIN microobjective was used for experiments displayed in this figure. b) Top: fluorescence image acquired with a camera of a two-photon extended shape projected onto a thick fluorescent slide. Scale bar: 10 µm. Bottom: intensity profile along the direction indicated by the white dashed line in the top panel. c) Fluorescence uniformity for extended shapes illumination under the different experimental conditions. p > 0.05, paired Student’s t-test (N = 10).
