Hemispherical arc-shaped scanning test frame capable of being used for laser countermeasure test

Abstract

The invention provides a hemispherical arc-shaped scanning test frame capable of being used for a laser countermeasure test, which comprises at least two gear rings, gear ring bases with the same number and at least cameras with the same number, the gear rings are of semicircular structures, and the radiuses of different gear rings are different; each gear ring is mounted on a gear ring base, and the gear ring bases are coaxially mounted and are driven by a motor to rotate around a shaft; each gear ring is provided with at least one mounting base for mounting a camera, the mounting base is also provided with a driving motor and a gear, the gear is meshed with the gear ring, rotates under the action of the driving motor and drives the mounting base to move on the gear ring, and the camera always points to the circle center position of the gear ring in the moving process. The scanning device is large in movement span, high in positioning precision and high in repeated positioning performance, the included angle between the inner ring and the outer ring can be adjusted, the scanning device can be positioned at any angle in the air, and it can be guaranteed that the device always points to the center of a to-be-detected object.

Description

technical field [0001] The invention relates to a device for reliability appraisal of laser countermeasure equipment, which is suitable for performance testing of laser interference imaging reconnaissance / guidance equipment and laser warning equipment. Background technique [0002] Laser jamming equipment is a kind of equipment that prevents or weakens its interception of intelligence information or loses its function by emitting laser light to photoelectric reconnaissance / guidance equipment. The anti-laser jamming test of reconnaissance guidance equipment and the laser jamming effectiveness evaluation of laser jamming equipment have always been experiments. key points of identification. [0003] However, the existing laser capture devices are greatly disturbed by the outside world, especially under different light intensities, and the imaging characteristics of laser interference need to be analyzed urgently. The current laser identification can only rely on outdoor operat...

[0003] However, the existing laser capture devices are greatly disturbed by the outside world, especially under different light intensities, the imaging characteristics of laser interference need to be analyzed urgently

The current laser identification can only rely on outdoor operations for identification, which is greatly affected by the environment, and the identification time is long. At the same time, the camera needs to be moved during the capture process, and the labor cost is high.

Other existing brackets generally have shortcomings such as small span and low centering accuracy, and it is difficult to simulate a wide range of angle tests from 0 to 180°. Moreover, the angle between the inner and outer rings of the existing brackets is generally fixed, and it is difficult to realize the clamping of the inner and outer rings. angle adjustable
