Embodiment Construction

[0017] The following description illustrates specific embodiments of the invention sufficiently to enable those skilled in the art to practice and reproduce it.

[0018] Under the premise of not changing the shape and internal structure of the original speed measuring system device, a device based on spherical reflection to expand the light curtain area is designed to realize the speed test of the large-caliber test prototype during the flight test of the test prototype.

[0019] like figure 1 Shown is a schematic structural view of the device for enlarging the area of ​​the light curtain based on spherical reflection in the present invention.

[0020] The device for enlarging the area of ​​the light curtain based on spherical reflection, including: a fan-shaped laser 1, a first hemispherical laser reflector 2, a second hemispherical laser reflector 3, a rectangular laser reflector 4, a photoelectric receiver 5, and a first light curtain bracket 6 , The second light curtain b...

Abstract

The invention discloses a light curtain area expanding device based on spherical reflection. The light curtain area expanding device comprises a fan-shaped laser, a first hemispherical laser reflector, a second hemispherical laser reflector, a rectangular laser reflector, a photoelectric receiver, a first light curtain support and a second light curtain support. A laser emitter and the photoelectric receiver are arranged on the first light curtain support; the first hemispherical laser reflector, the second hemispherical laser reflector and the rectangular laser reflector are arranged on the second light curtain support; and the first hemispherical laser reflector and the second hemispherical laser reflector are located at the two sides of the rectangular laser reflector respectively. Theinvention further discloses a using method of the device. The speed measurement range of a speed measurement system device is enlarged by changing the positions of the laser emitter and the photoelectric receiver, the photoelectric receiver amplifies the laser beams, the laser beams are superposed to form a large laser beam, and speed measurement of a large-caliber test prototype is achieved.

Description

technical field [0001] The invention relates to a measurement technology, in particular to a device for enlarging the area of ​​a light curtain based on spherical reflection and a method for using the same. Background technique [0002] In the test verification stage of the test prototype, in order to demonstrate whether the launch speed of the test prototype meets the design requirements, a flight speed test is required to measure the exit speed requirements of the large-diameter test prototype. [0003] However, there is currently a lack of a measuring device for testing large-diameter test prototypes to meet the needs of flight speed testing. Contents of the invention [0004] The technical problem solved by the present invention is to provide a device for enlarging the area of ​​the light curtain based on spherical reflection and its use method, by changing the position of the laser transmitter and the photoelectric receiver to increase the speed measurement range of t...
