PCT No. PCT/SU88/00174 Sec. 371 Date May 10, 1990 Sec. 102(e) Date May 10, 1990 PCT Filed Aug. 30, 1988 PCT Pub. No. WO90/02420 PCT Pub. Date Mar. 8, 1990.The measurement method according to the invention comprises coding conversion of the spatial intensity distribution of electromagnetic radiation into an electric signal with the aid of the stationary Josephson effect, setting this signal to be variations in the maximal Josephson current produced by the electromagnetic radiation under study, varying the coding conversion parameters by applying an external magnetic field to junction (2), with spatial frequencies of the Josephson current density as a function of Josephson junction (2) coordinates serving as these coding conversion parameters, measuring the electric signal as a function of these coding conversion parameters, and decoding injective mapping of the measured dependence of electric signal from the coding conversion parameters with the aid of the integral Fourier transform.
