Background
The measurement of the fragment speed can be divided into an instantaneous speed measurement method and an average speed measurement method in principle. The instantaneous velocity of a fragment is difficult to measure directly, so it is usually measured using an average velocity measurement.

When the on-site test is carried out, the power supply of the linear laser 2 is switched on, and the laser light source emits laser to form a single fan-shaped light curtain area. The front and rear two linear lasers 2 form front and rear pairs of light curtain regions. Then, the storage type test host 1 is completely buried, and only the linear laser 2 is exposed out of the ground surface, so that the storage type test host 1 is protected from being hit and damaged by the fragment 6. When in security protection, the device is required to form a light curtain which is vertical to the ground. When the fragments 6 pass through the effective area 5 of the light curtain, laser irradiates the fragments to form reflection, and the reflected laser signals are received by the photoelectric detector 3, so that the photocurrent changes, and pulse triggering signals are generated after the photocurrent passes through the signal processing circuit. Because the fragment speed is very fast, two pulse signals which occur at different time can be formed in the paired light curtain effective areas, and the instantaneous speed of the fragment 6 at the distance can be calculated only by reading the time difference of the two similar pulse signals because the distance between the two target slits 4 of the whole device is fixed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but also to cover any modifications or equivalent changes made in the technical spirit of the present invention, which fall within the scope of the present invention.
