This limit can be circumvented by making use of multiphoton detection of correlated $N$-photon states, having an effective wavelength $\\lambda_p/N$. But the required $N$-photon detection usually renders these schemes impractical. To overcome this limitation, recently, so-called optical centroid measurements (OCM) have been proposed which replace the multi-photon detectors by an array of single-photon detectors.
