FIELD: physics.
SUBSTANCE: device contains: interface for receiving the data stream received from the electromagnetic radiation reflected by an object, a converting means to transfer the characteristic signal to the portable signal, wherein each of, at least, two differential components can be obtained through the appropriate arithmetic conversion containing partial subtraction of one of the three absolute components of the remaining absolute components, wherein the arithmetic conversion additionally contains the coefficients for each of the two differential components, that partly have an amount essentially equal to zero, and wherein the two differential components provide the possibility of partial suppression of the clutter signal part in the portable signal; and an extracting means for extracting the partially periodic vital signal of the two differential components in the portable signal.
EFFECT: improving accuracy of obtaining the object vital signals.
