Spatial modulation tomography setup. HeNe: helium-neon laser. In sample path (red): BS beamsplitter, GM galvanometer-controlled mirror, C condenser lens, θ beam tilt angle, S sample, OBJ objective lens, and DBS dichroic beamsplitter. In reference path (blue): BE beam expander. TL tube lenses, CMOS camera, and L1, L2, L3 lenses. CCD: camera for bright-field and fluorescence imaging (light path shown by dotted line). Not shown: illuminators and filters for bright-field and fluorescence imaging.
