Abstract: The present disclosure relates to a method and apparatus for performing a spatial domain-based optical convolution operation. A method of performing a convolution operation according to an embodiment of the present disclosure may comprise: performing a first optical Fourier transform on a spatial domain image; performing a second optical Fourier transform on a spatial domain kernel; performing an element-wise product operation between a result of the first optical Fourier transform and a result of the second optical Fourier transform; calculating a convolution result by performing a third optical Fourier transform on a result of the element-wise product operation; and obtaining data based on the convolution result.
