The imaging and timing properties of {\\gamma}-ray emission from electromagnetic cascades initiated by very-high-energy (VHE) {\\gamma}-rays in the intergalactic medium depend on the strength B and correlation length {\\lambda}B of intergalactic magnetic fields (IGMF). Aims. We study the possibility of measuring both B and {\\lambda}B via observations of the cascade emission with {\\gamma}-ray telescopes. Methods. For each measurement method, we find two characteristics of the cascade signal, which are sensitive to the IGMF B and {\\lambda}B values in different combinations.
