Fig. 2: HSPM experimental setup render and schematic.

In (a) a render of the implemented HSPM is shown, the M-AL, detailed in the yellow zoomed inset is placed into the imaging system conjugated aperture plane. In (b), adapted from Ref32, a detailed schematic of the optical set-up is provided, the built system is configured by the imaging modules, the illumination coupling module M-Ⓐ ensures the DMD incident angle, the projection module M-Ⓑ configures the microscope setup needed to demagnify the encoded Hadamard patterns on the DMD over the sample plane, finally the reflection module M-Ⓒ ensures a proper collection of the scattered light by the sample. A detailed list of materials and step by step construction of the implemented HSPM can be found. The detailed element in the schematics corresponds to Api aperture ith, Mi mirror ith, Li lens ith, M-AL Deformable lens, FD field diaphragm, TLi tube lens ith, BSi beam splitter ith, MOi microscope objective ith, BD bucket detector.
