APPARATUS FOR MEASURING VELOCITY OF MOVING OBJECT USING VISAR OR ORVIS
The present invention refers to VISAR ORVIS or using moving object using video sensor to device are disclosed. VISAR basic general outline of a silver object velocity profile (velocity profile) (velocity interferometer system for any reflector) analysis for measuring light reflected at the surface of the moving object using Doppler movement which, having two types of assays is basic components 1) light reflected from an object of fringe (fringe) and determine a move, 2) calculating the speed of object based on measured fringe movement comprising the following steps. The VISAR 1960's leg opening at each projectile impact plates (plate provided impact) and 1970's free surface movement (velocity history) has been developed as a tool for measuring speed of history. VISAR analysis pertaining to spatially or diffusion reflected in movement speed when the surface with elapse of time according to obtain using laser interferometer, substantial main unique method only min of the measures observation connected to the oscilloscope. 1980 To seconds after high-speed developing portion is VISAR assays (streak camera) hydroentangling camera capable of recording by adopting the optical version of an interferometer fringe movement VISAR assays (optical version) in ORVIS (optically recording velocity interferometer system) has been developed. Method and device for measuring fringe movement, laser (coherent light) is irradiated on the surface of the motion state object is generated interference storehouse, interferometer in the reflected object surface through the substrate. The relative phase difference between the two arms in the interferometer by fringe pattern are generated, the spatially decomposed fringe pattern may be measured as a function of time for hydroentangling camera body. Amount of movement of the object has a fringe pattern correlation flushes, specifically, (λ 0) defined wavelength of laser Doppler effect of interference when irradiated to moving object reflected light (λ) such as the relationship between the following [expressions 1] given substrate. [Mathematical equation 1] [Mathematical equation 1] v in movement of an object of which is speed, c is the luminous flux are disclosed. On the other hand, when the following [equations 2] to [expressions 1] v ≪ c such as can be represented. [Equations 2] [2 Expressions] object such as the speed of the hydroentangling camera recorded directly proportion calculating a size of the amount of movement of vertically aligned object speed history can be determine fringe amount of movement, the, impact wavefront (shock front) or free surface be a motion state of the object. The compared voltage is shock wave principle ORVIS VISAR or fast moving object measurement surface speeds etc. are used. Figure 1 shows a device according to moving object using video sensor of the conventional techniques are disclosed. 1 Also illustrated as shown with, prior art speed measuring device is, the amount of movement of the interference fringe wavelength using Doppler effect for detecting optical system (10) which, interference optical system (10) includes generating actual interference storehouse irradiating laser beam with the object (1) a portion of the reflected light reflected from the transmitting and reflecting a portion the beamsplitter (11) on, beamsplitter (11) transmitted beams reflect number 1 arm mirror (12) on, number 1 arm mirror (12) fittable into the path difference on having a beamsplitter (11) to the other cancer mirror reflected light of number 2 (13) on, beamsplitter (11) number 1 on cancer mirror (12) that is located between the etalon (14) and, number 1 arm mirror (12) number 2 on cancer mirror (13) each reflected in the resulting interference light meter (60) for reflecting mirrors reflected (15) having a predetermined wavelength. Reflecting mirrors (15) reflected from the interference meter (20) communicated, meter (20) is vertically aligned for measuring the amount of movement of the moving object (1) to determine the speed of. Etalon (14) by means of which the position of the interface by controlling selective regulation of its thickness, the transmission of light can be made uniform of the meter. A measurement device for measuring velocity of such known degree of roughness or surface distortion and holds for laser wavelength is reduced compared to the measuring beam reflected well such as mirror if the temporal, spatial interference fringe hereinafter for the measured rates to an electromagnetic wave free. However measurement surface when an exposure is performed is the reduction as well as scattering measuring signal of an electromagnetic wave is performed sharpness interfering patterns and rates, in addition some scattering light influencing of the same meter measurement error also other. In particular in the case of unexploded ordnance or large shock wave experiment using laser measurement object object protection device a sufficient distance to an object of interest should one the ORVIS VISAR or interference between optical signal beam is long distance by an negative signal before arcing occurs to the TFTs. In order to solve this signal reducing or interfering patterns of transmission signals using a door number sharpness degradation site and can be reduction of compensation, this example Figure 2 shows a conventional technique into moving objects thereby measuring 06 etc. in another example of a device. The reference 2 also, other conventional techniques in (or ORVIS) VISAR interference optical system (10) and the measuring object (1) between the condenser lens (31) arranged, interference optical system (10) on meter (20) between the collimator lens (32) is disposed on the signal light according to generate a distance away is equal to prevent a sharp reduction in the size. The focusing lens to scatter signals on transmission scheme provides site selection screen to select signal sensor portion in such a way that although accurate measurement can be focused in sensor position until lens of which at adjustable distances, the measurement object such as unexploded ordnance or laser shock wave and their distance must satisfactorily ensure when optical lens for aligning parts, and requires a large tool on, is absorbed due to the air flow signal is converter easy one.
