Continuously distributed sensors (CDS) disclose a principally new way to provide space distribution measurements for different physical fields, such as temperature, velocity and light intensity fields. The design of onedimensional CDS and corresponding pulse measurement method are proposed. The numerical algorithm implementing the pulse measurement method are obtained based on inverse operator problem reduced to the optimal control of parabolic partial differential equation coefficients. The algorithm has been numerically studied for two methods of regularization: Tikhonov and iterative. The results of the numerical simulations show that for the low level of the experimental noise (0.1-0.5%) the proposed algorithm is able to restore the space distribution of the measuring physical field with 0.6-4% accuracy. It is shown that appropriative choice of materials for microfilm CDS allows to obtain the electrical relaxation time within the range 10(-2)-10(-5) s, within which the physical fields under measurement could be considered as quasistatic.
