Abstract : Scanning probe microscopy and gradient imaging are two techniques for imaging at sub-wavelength spatial resolution. Gradient imaging in the form of magnetic resonance imaging (MRI) has so far been demonstrated only in the radio- and microwave frequency domains. An extension of MRI to optical frequencies for imaging (semi-) transparent objects is of interest because an optical photon detection process is inherently more sensitive than magnetic induction detection, potentially leading to increased spatial resolution. Rare-earth ions incorporated into a crystalline host are promising as a prototype system for demonstration of high spatial resolution OMR1. In resonance imaging spatial resolution is obtained by focussing in the frequency rather than space domain and thus spatial resolution is not directly dependent on the wavelength of the exciting waves, A simple estimate for the minimum resolvable detail size can be given by considering magnetic resonance imaging of centers containing a Zeeman doublet (lower level 0 and upper level 1).
