Fig. 2. Optical resolution in tomographic AM.

a étendue-limited optical resolution. b Experimental measurement points on-axis (blue circle), at mid-field, (red square) and edge of field (yellow triangle) of the modulation transfer function (MTF) in the build volume of our tomographic printer. c Experimental MTF as a function of the spatial frequency 8 mm ahead of the focal plane, d at focus and e 8 mm after focus. The error bars represent the standard deviation of five repeated measurements at a point at the edge-of-field point at focus, and the error value for the other points were assumed to be the same (see Supplementary Note 3).
