Schematic of the optical setup. ND filter: neutral density filter, Sp. lens: spherical lens, SLM: spatial light modulator. The blue lines represent the excitation; the green lines represent the fluorescence emission. Removable mirror allows switching between imaging arms via detection objective 1 and 2. The filter is also removable to allow for direct imaging of the illumination light. The sample chamber between the illumination objective and detection objective 1 is drawn in more detail on the right side of the schematic showing the position of the scattering layer and of the glass capillary containing the sample
