Example Embodiment

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0011] figure 1 It is a schematic diagram of the principle of the present invention, and the launch angle from the device 1 is θ 0 The two laser beams 10 and 11, the direction of the laser beam 10 represents the axis 5 of the platform A1, and the two laser beams are projected on the reflective screen 4 at a distance D to form bright spots 8 and 9, which are diffusely reflected by the reflective screen. The television observation device on platform A2 detects the imaging. The baseline distance between platform A1 and platform A2 is H. The position of the TV electric cross represents the axis position of the TV detector and is also the reference center during measurement. When the platform A1 is parallel to the platform A2, the axis, that is, the electric cross is 6. When it is not parallel, the position of the electric cross is ass...

Abstract

The invention discloses a laser diffraction type multi-system axis parallelism detecting device. The laser diffraction type multi-system axis parallelism detecting device is mainly characterized in that laser beams capable of being detected by a television detector, such as red laser and green laser, are transmitted, after passing through collimating lens, the laser beams enter a diffraction grating device to be diffracted to obtain diffraction laser beams, wherein the direction of zero-level diffraction laser is identical to that of the axis of a gun barrel, the diffraction laser beams are projected to a distant non-cooperative reflecting screen via a lens system to form a diffraction image. The diffraction image enters a view field of a radar/photoelectric television observation device via diffuse reflection to image, an angle between the diffraction image and an electric cross reference is calculated from the image, and errors of axis parallelism between a gum and radar/photoelectricity are determined from data processing. The laser diffraction type multi-system axis parallelism detecting device has the advantages that the device is not limited by distances of baselines among platforms during usage, and can be used for detecting the axis parallelism of a plurality of devices simultaneously.

Description

technical field [0001] The invention belongs to the technical field of photoelectric testing, and in particular relates to a photoelectric testing instrument for detecting axis parallelism between a cannon and radar / photoelectric observation and tracking equipment in a cannon weapon system. technical background [0002] With the development of automatic control technology and photoelectric technology, the modern self-propelled artillery weapon system is equipped with a tracking radar / photoelectric sighting device fire control system. The tracking radar / photoelectric aiming device can find and capture the target at a relatively long distance and accurately determine the target position, and transmit the target information to the artillery follow-up system in time. Shooting accuracy and artillery hit accuracy. The parallelism of the axis between the radar / photoelectric and the artillery determines that the accuracy of the target information provided by the radar / photoelectric...
