1. A method comprising:
modulating a beam of light through a spatial light modulator configured to convert the beam of light to an Airy beam, the spatial light modulator being rotatable and positioned at a first angle relative to a sample;
obtaining a first perspective view of the sample by a detector, the first perspective view being generated by the Airy beam interacting with the sample on a focal plane;
rotating the spatial light modulator such that the spatial light modulator is positioned at a second angle relative to the sample;
obtaining a second perspective view of the sample by the detector, the second perspective view being generated by the Airy beam interacting with the sample on the focal plane; and
reconstructing a volumetric three-dimensional view of the sample using the first perspective view and the second perspective view;
wherein the spatial light modulator comprises a spatial filter configured to suppress Airy side lobes of the Airy beam.
