Claim 1:
2. The holographic three-dimensional multi-spot light stimulator device according to claim 1, wherein the three-dimensional light stimulation holographic optical system includes a second spatial light modulator, a polarization-dependent bifocal lens, a polarization-dependent bifocal lens with a diffraction grating, or a volumetric holographic optical element, the fluorescence signal light is self-interfered to acquire three-dimensional fluorescence distribution information using a hologram of an interference fringe pattern having an equal inclination angle, and these are repeated; and
wherein the control unit in the three-dimensional light stimulation holographic optical system is configured to identify the positions of the stimulation target objects within a range of ±100 μm from a depth focal position based on the three-dimensional fluorescence distribution information, and to calculate the light stimulation hologram for forming light spots simultaneously at the positions of the stimulation target objects and to generate the hologram by controlling the first spatial light modulator.
