Abstract: A dual-function penetrator liner for a multifunctional warhead. A dome-shaped outer portion is disposed in an inner front end of a warhead body to be concave in a direction opposite to a direction in which the warhead body is fired. A fastening portion is disposed in an outer circumferential direction of the outer to fasten the outer portion to the warhead body. A conical central portion is enclosed by the outer portion to protrude in a direction opposite to the direction in which the warhead body is fired. The outer portion and the central portion are concentric.

Abstract: Disclosed is a fiber optic sensor system for sensing strain of the structure by using a wavelength swept fiber laser as a light source and using a fiber Bragg grating sensor as a fiber optic sensor, comprising: a reference fiber Bragg grating sensor, a fiber Bragg grating sensor array being branched from the reference fiber Bragg grating sensor through a coupler; a strain rate measuring coordinate signal-outputting means adapted to output an optical signal having a certain wavelength, an optical detector being connected to the coupler from which the fiber Bragg grating sensor group and the strain measuring coordinate signal-outputting means are branched for detecting output signals generated from the strain measuring coordinate signal-outputting means.
