We demonstrated that sub-micron resolution, high dynamic range LiF detectors, based on the formation under EUV and soft X-ray irradiation of optically active color centers, allowed applying a single shot imaging technique for characterizing relativistic high order harmonic beams, generated by an oscillating electron spikes formed in underdense gas jet plasma created by relativistically self-focusing laser pulses. The LiF film was used for near-field diffraction imaging of the HOH beam and investigation of its coherent properties. The focusability of the HOH beam was investigated using spherical Mo/Si mirror and LiF crystal. Using such technique the sizes and complexity of the HOH source structure have been measured.
