Abstract
The present invention concerns an optical system for spatiotemporally shaping the wavefront of the electric field of a light beam () to be projected into a target volume (), where the propagation axis is axis z, to create 3D patterned illumination in the target volume (), comprising a pulsed laser source, configured to have an illumination pattern whose transversal surface at the target volume being superior to the diffraction limit of the optical system, at least one intermediate optical element () which is a dispersive grating for performing temporal focusing of the light beam (), located, on the propagation axis (z), where an image of the illumination pattern is formed, for modulating the phase and/or the amplitude of the electric field of the light beam, and a second optical element () which is a spatiallight modulator for modulating the phase of the electric field of the input light beam, and for realizing spatiotemporal multiplexing to create 3D patterned illumination in the target volume () by replicating the illumination pattern, so as to have several replicated illumination patterns in the target volume (), and controlling the position with transversal coordinates X, Y and axial coordinate Z of each replicated illumination pattern in the target volume ().
