In its aperture\u2010type implementation, the local field is collected through a sub\u2010wavelength aperture and an optical fiber. The choice of this fiber imposes an inherent trade\u2010off between signal strength and phase fidelity. Single\u2010mode fiber probes maintain phase fidelity but suffer from low signal intensity, whereas multimode fiber probes offer higher throughput but introduce severe phase distortions. Here, we present phase\u2010conjugation interferometric NSOM (PCI\u2010NSOM), which overcomes this limitation. The output field of the multimode fiber is measured by off\u2010axis holography, and its phase conjugate is displayed on a spatial light modulator, converting the scrambled speckle into a planar wavefront that focuses to a single point in Fourier space. At the focal pixel of the detector, the correction enhances the intensity by up to \u223c165\u2010fold. We demonstrate PCI\u2010NSOM by imaging surface plasmon polaritons on a gold grating, obtaining accurate phase maps where uncorrected multimode collection fails through modal dispersion and single\u2010mode collection through a low signal\u2010to\u2010noise ratio. PCI\u2010NSOM thus provides a practical route to high\u2010sensitivity phase\u2010resolved nanoscale optical
