As shown in Fig. 1, the proposed accelerometer is mainly composed of three mass blocks, four flexible hinges and one the action of ambient vibration, the middle block with mass m m will vibrate in the vertical direction, and the other blocks with masses m j will rotate around the flexible hinge center point A at the same time. The sensitive part of the accelerometer is the FBG which

The government component of the GDP accounts for the central government expenditure in national defense and non-defense, as well as State and local government’s expenditure estimates. Government purchases of goods and services are a compensation of government employees and purchases from businesses and abroad.

The Diffraction Grating. After light passes through the slit, a set of lenses or mirrors collimates the light (makes all light rays parallel to the optical axis) and delivers the light to the diffraction grating. A diffraction grating consists of a material containing a periodic variation in one of its optical properties.
Optical fiber sensor (OFS) is a new type of sensor with light wave as a carrier and optical fiber as a medium, possessing high sensitivity, interference immunity, anti-corrosion, high-pressure resistance and other merits, thus being widely used in national defense, petrochemical, electric power, infrastructure, medical, etc..

Defense Expenditures and National Well-Being competitors such as Japan and West Germany, who do not devote as large a proportion of their resources to defence, have outcompeted the United
PDF | Grating lobe effect often exists in the measurement and simulating of phased array antenna's directional pattern. The emergency of grating lobe effect often leads to angle multi valuedness
The Fraunhofer diffraction equation is an approximation which can be applied when the diffracted wave is observed in the far field, and also when a lens is used to focus the diffracted light; in many instances, a simple analytical solution is available to the Fraunhofer equation – several of these are derived below.
The quality and spacing of the grooves are crucial to the performance of the grating, but the basic grating equation may be derived by supposing a section through the grating surface, normal to the ruling direction as a sawtooth pattern, shown below.

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
“The diffraction grating is a useful device for analyzing light consists of a large number of equally spaced parallel slits.”Its working principle is based on the phenomenon of space between lines act as slits and these slits diffract the light waves thereby producing a large number of beams which interfere in such a way to produce spectra.
Abstract. In search of a way to accurately measure time of arrival of detonation fronts, we have been using an electronic streak camera equipped with a light intensifier to record intensity-time histories of the light that is emitted when a detonation front emerges through the surface of high explosives in contact with various environments.
The initial surge in microwave technology development was driven by the military needs of the second world war. The tremendous effort that went into development of radar during World War II generated a great body of knowledge on the properties of microwaves and related technologies. Much of this
