Abstract: The nonprobe nearfield optical microscope is introduced in this paper, and the processing method and realization of the images are discussed. Based on the theory of Hadamard Transform imaging, the nonprobe nearfield optical microscope, which replaces the fiber probe with the nanometer multiaperture encoding mask, has a high optical signaltonoise ratio. The research shows that the nonprobe nearfield optical microscope can detect the evanescent nearfield wave effectively and the image with a superdiffraction limiting resolution can be obtained.All this will provide a new method for the research of the nearfield optics.
