Embodiment 1
[0036] Embodiment 1: as figure 2 , 3 As shown, a structured illumination microscopic imaging system based on an integrated photonic chip, including a light source 1, an integrated photonic chip 3, a sample placement table 4, a microscope objective lens 6, an optical filter 7, a photoelectric detector 8, and a computer processing system 9 and the control system 10, the light source 1 is connected to the integrated photonic chip 3, the integrated photonic chip 3 is arranged under the sample placement platform 4, the microscopic objective lens 6 is arranged above the sample placement platform 5, and the optical filter 7 is arranged above the microscopic objective lens 6, The photodetector 8 is located above the filter 7; the sample placement platform 4 is fixed with the sample 5 to be tested, and the sample placement platform 4 holds a glass slide, and the slide glass is the sample 5 to be tested, and the sample placement platform 4 is Transparent; the light emitted by the ligh...
Embodiment 2
[0043] Embodiment 2: as image 3 As shown, the integrated photonic chip structure adopted in the present invention includes a grating coupler 301, an optical beam splitter 302, an optical waveguide 303, an optical switch array 304, an optical phase shifting array 305 and a grating diffraction array 306 integrated into a millimeter-scale chip . The input light enters the 1×3 beam splitter 302 through the grating coupler 301 and becomes three beams with equal power, and then enters the 3×8 optical switch array and is output from the specified output port. The phase shifting array 305 is used to control the phases of the three light beams entering the diffraction grating array 306 respectively. After being diffracted by the grating, the three beams interfere in the space perpendicular to the surface of the chip to form a three-dimensional structured light with a specific periodic distribution.
Embodiment 3
[0044] Embodiment 3: as Figure 4 Shown is a schematic diagram of the arrangement of the light diffraction array used in the present invention. Figure 4 a is arranged in a linear array, Figure 4 b is a polyline array arrangement, Figure 4 c is arranged in a curved array.
