The advanced multispectral method is developed for formation and recovery of the image of a hypodermic on the basis of function of a detuning and its algorithm realizing. The method reduces distorting influence of change of characteristics of skin on image formation. Use of function of a detuning allows to make processing without observance of rigid requirements to the accuracy of a choice of lengths of waves on which images and, respectively, providing a preset value of the relation of values of optical thicknesses of skin are formed.

  For the previously proposed microphone system with adaptive control algorithm was investigated directional characteristic accuracy of the determination the angle of the sound source. The dependences of the absolute deviation on the angle of signal arrival of the sound source, defined by the spread of sensitivities directional microphone system were received.
