We propose to use intensity correlation microscopy in combination with structured illumination to image quantum emitters that exhibit antibunching with a resolution reaching far beyond the Rayleigh limit. Combining intensity measurements and intensity autocorrelations of order m creates an effective PSF with the FWHM shrunk by a factor of √m [1,2]. Structured Illumination microscopy [3] on the other hand introduces a resolution improvement by a factor of 2 by the principle of moiré fringes. We show that for linear low-intensity excitation and linear optical detection the simultaneous use of both techniques leads to an in theory unlimited resolution power with the improvement scaling favorably as m + √m [4]. This yields the technique to be of interest for microscopy including imaging of biological samples. We present the underlying theory and simulations that demonstrate the increased resolution power, and point out requirements for an experimental implementation. [1] T.
