  • Imaging device comprising spatial light modulator and imaging method thereof
    Patent number: 11962913
    Abstract: An imaging apparatus includes a light source, a spatial light modulator, a Fourier transform optical system, a photodetector, and a control unit. The control unit sets a first region and a second region on a modulation plane, acquires a light intensity value by setting a light amplitude modulation pattern in the first region and setting a light amplitude modulation in the second region to a non-zero predetermined value, acquires the light intensity value by setting the light amplitude modulation pattern in the first region and setting the light amplitude modulation in the second region to zero, acquires the light intensity value by setting the light amplitude modulation in the first region to zero and setting the light amplitude modulation in the second region to the predetermined value, and acquires a complex amplitude image of a region of an object corresponding to the first region.

  • Imaging device and imaging method
    Patent number: 11852795
    Abstract: An imaging apparatus includes a light source, a spatial light modulator, a Fourier transform optical system, a photodetector, and a control unit. The control unit sets a first region and a second region on a modulation plane of the spatial light modulator, sequentially sets a plurality of light phase modulation patterns in the first region, sequentially sets a plurality of uniform phase shifts in a region other than the first region when setting each light phase modulation pattern in the first region to acquire a light intensity value, and acquires a phase image of a region of an object corresponding to the first region using a phase shift method.
