Fig. 2: Schematic configuration and numerical simulation results of coherent illumination optics.

a Projection illumination optics proposed in this study. b Conventional focusing optics in off-axis configuration. BDA beam-defining aperture, FZP Fresnel zone plate, OSA order-sorting aperture. c, d Calculated wave field of each optics configuration at the sample plane. Brightness and hue represent the amplitude and phase distributions of the waves, as shown in the inset in c. The inclination of the wavefront was corrected, as shown in Supplementary Fig. 1. Scale bars indicate 2 μm. e Horizontal intensity profile of wave field c in red and d in blue, respectively. Each profile is normalised with its maximum intensity, and the wave field (c) was 2.4-times higher than that of (d). Upper graph is drawn in linear scale, and the lower is drawn in logarithmic scale.
