Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a laser spot detection device. Background Art

[0002] The laser light finder of the "reconnaissance and strike integrated" airborne optoelectronic pod is the core sensor for illuminating enemy targets and guiding semi-active laser-guided weapons to achieve precise strikes. Since the laser spot cannot be directly observed by the naked eye, it needs to be observed through a spot detection device.

[0003] The light spot detection device can be used to check the consistency of optical axes of laser light meters, visible light cameras and infrared thermal imagers; it can be used to check the light spot shape of laser light meters when airborne optoelectronic pods are used for long-distance illumination; it can be used to check the indication accuracy and tracking stability of airborne optoelectronic pods when they are in flight; during target testing, it can record the positional relationship between the laser spot of the airborne optoelectronic pod and the target plate, and provide analysis video for the target test results.

[0004] In order to find the best image for spot detection, it is necessary to adjust the height of the camera and lens of the laser spot detection device. Application No. 201611073316.9 discloses a portable laser spot detector and its measurement system, but does not consider the camera and lens height device of the laser spot detection device. In specific applications, the image effect is general and the spot detection accuracy is relatively general. Application No. 202320872162.9 discloses a portable laser spot monitor. By setting an electric telescopic rod, the mounting plate can be controlled to move up and down to adjust the height of the camera and lens, and then the angle of the camera is adjusted by the rotating structure to facilitate finding the best image for spot detection. However, the electric telescopic rod has a small range of motion, and the adjustment of the camera and lens height is limited. If the electric telescopic rod has a larger range of motion, the entire device will be larger, the integration will be lower, and the portability will be lost. In addition, since the camera and lens rotate in the device, the external structure of the device is easy to block the camera and lens, affecting the spot detection work. Utility Model Content
