Measurements are reported of high frequency cross-spectra of signals from the Fermilab Holometer, a pair of co-located 39 m, high power Michelson interferometers. The instrument obtains differential position sensitivity to cross-correlated signals far exceeding any previous measurement in a broad frequency band extending to the 3.8 MHz inverse light crossing time of the apparatus. General experimental constraints are placed on parameters of a set of models of universal exotic spatial shear correlations, with a sensitivity that exceeds the Planck scale holographic information bound of space-time position states by a significant factor. Current status and future plans are discussed.
