Abstract

The invention relates to a device and method for detecting light-screen parameters of light-screen targets. At present, a method for measuring the distance between two light-screen surfaces is low in measuring precision, the two light screen surfaces are not strictly parallel, high-precision measurement on a shot flying speed cannot be realized, and a light-screen target and a laser target in use need regular detection on the flatness of the screen surfaces and the parallelism and the distance between the two screen surfaces. The detecting device for detecting the light-screen parameters of the light-screen targets is characterized by comprising a datum plane assembly and a distance-measuring datum plane assembly, wherein the distance-measuring datum plane assembly comprises a second laser plane projector, a second plane normal laser projector and a high-precision laser distance measurer, which are arranged on a second precise platform; the datum plane assembly and the distance-measuring datum plane assembly are oppositely arranged in parallel at equal height. The detecting device and the detecting method disclosed by the invention can be used for overcoming the defects that the measurement for the distance between two targets has large errors, that the light-screen surface parallelism cannot be ensured, and the like.

Description

technical field [0001] The invention belongs to the technical field of conventional weapon shooting range testing, and mainly relates to a light curtain parameter detection device for measuring projectile velocity, in particular to a detection device for measuring the flatness of the light curtain target light curtain and the parallelism and distance between two light curtains The device and method are used to detect the parallelism and target distance of two light curtains and target light curtains used for speed measurement. Background technique [0002] In the production and development of weapons and equipment, the flying speed of the projectile is a key parameter that needs to be tested frequently, and it is also a must-test item in product inspection. The speed quantity is the basic parameter of the national defense industry, and the accuracy of the measurement of this parameter directly determines the manufacturing level of the national defense industry. For the test...
