As shown in fig. 1 and 2, the imaging system of the embodiment of the present application includes a zoom optical system 2 and an imaging assembly 1, the imaging assembly 1 being configured to image a light beam from the zoom optical system 2.
The imaging assembly 1 includes a camera 11 and a mount 12, the zoom optical system 2 and the camera 11 being arranged in order along an optical path, the mount 12 being adapted to be connected to the zoom optical system 2, the mount 12 being provided with a first adjustment portion 121, the camera 11 being provided with a second adjustment portion 1121 slidably fitted with the first adjustment portion 121, the second adjustment portion 1121 being slidable relative to the first adjustment portion 121 to bring the camera 11 closer to or farther from the zoom optical system 2.
Among them, the zoom optical system 2 is one of the main parts of the system for processing and adjusting the light beam to meet specific imaging requirements. By the zoom function, the optical system can change the focal length, thereby changing the magnification or viewing angle of imaging.
The zoom optical system 2 can receive visible light and near infrared energy in the 400-950 nm spectrum band and transmit the visible light and near infrared energy to the target surface of the detector in a converging way, and the zoom optical system 2 can have the functions of zooming, focusing, diaphragm adjustment and optical filter switching.
The zoom optical system 2 may be a manual focusing system, or may receive a driving voltage of the servo control board 3 to perform a corresponding adjustment action.
The imaging assembly 1 is used to convert a light beam from the zoom optical system 2 into an image. Wherein the camera 11 is the core of the imaging assembly 1, the camera 11 is used for capturing and recording images formed by light beams, and the mounting frame 12 is used for fixing and supporting the camera 11 and is connected with the zooming optical system 2 so as to improve the relative stability of the camera 11 and the zooming optical system 2.
The mounting frame 12 is further provided with a first adjusting portion 121, and the first adjusting portion 121 is used for being matched with a second adjusting portion 1121 of the camera 11 to achieve position adjustment of the camera 11.
The first adjustment portion 121 and the second adjustment portion 1121 are slidably fitted to each other so that the camera 11 can move relative to the zoom optical system 2. By adjusting the second adjusting portion 1121 so that the second adjusting portion 1121 slides with respect to the first adjusting portion 121, the position of the camera 11 can be continuously and smoothly adjusted, so that the user can finely adjust the position of the camera 11 as needed to be close to or away from the zoom optical system 2. This adjustment provides a flexible adjustment range, and the distance between the camera 11 and the zoom optical system 2 can be changed as needed, thereby optimizing the imaging effect.
The first adjusting portion 121 is located on the mounting frame 12, and may be a sliding rail or a sliding groove structure, and has stable supporting and guiding functions. The second adjusting portion 1121 is located on the camera 11, and the second adjusting portion 1121 is designed with a sliding portion, such as a slider or a roller, that is matched with the first adjusting portion 121 so that the two can be smoothly and precisely moved relatively. In addition, the design has higher durability and reliability and can bear a certain degree of vibration and impact.
In practical applications, when the position of the camera 11 needs to be adjusted, the user can manually or mechanically operate the second adjusting portion 1121 to slide the second adjusting portion 1121 on the first adjusting portion 121, and meanwhile, the electronic control system can be combined to realize automatic position adjustment and remote control, so that the flexibility and convenience of the imaging system are further improved. The sliding motion of the second adjustment portion 1121 sliding on the first adjustment portion 121 can control the distance between the camera 11 and the zoom optical system 2, thereby achieving fine adjustment of the focal length, the angle of view, or the working distance. After the adjustment is completed, the camera 11 and the mounting frame 12 can be fixedly connected through a threaded connecting piece 112 such as a bolt or a fastener such as a buckle, so that the movement of the camera 11 relative to the mounting frame 12 in the later stage in the use process is reduced, and the imaging effect is reduced.

It should be noted that, in the case of poor imaging quality of the imaging system, the second adjusting portion 1121 may be adjusted to slide relative to the first adjusting portion 121 by adjusting the second adjusting portion 1121, so as to fine-adjust the distance between the camera 11 and the zoom optical system 2 as needed, and this adjustment process may be implemented at any node before and after the factory, and the structure is simple, and the adjustment is convenient. Once the camera position is confirmed, the position between the camera 11 and the zoom optical system 2 may not be moved any more.
In some embodiments, as shown in fig. 3, the first adjusting portion 121 is a long hole having one end close to the zoom optical system 2 and the other end remote from the zoom optical system 2, and the second adjusting portion 1121 includes a sliding portion at least partially located in the first adjusting portion 121 and a fitting portion to which the sliding portion is fitted and connected.
Wherein the first adjustment part 121 has a long hole shape, which allows the second adjustment part 1121 to linearly slide therein. One end of the slot is close to the zoom optical system 2 and the other end is remote from the zoom optical system 2, and this arrangement provides sufficient space for movement of the camera 11 so that it can be close to or remote from the optical system.
The design of the long hole takes into account the relative positional relationship between the zoom optical system 2 and the camera 11. By adjusting the position of the second adjusting portion 1121 on the long hole, the distance between the camera 11 and the zoom optical system 2 can be well controlled, and the focus and the field of view imaged by the camera 11 can be further adjusted.

The mating portion serves as a connecting and fixing function for connecting the sliding portion with the camera 11. Like this, when the sliding part moves in first adjustment portion 121, the cooperation portion can drive camera 11 and carry out corresponding removal, and it is convenient to adjust, and the flexibility is high, helps realizing higher quality's imaging.
The outer contour of the sliding part is profiled with the two ends of the long hole.
The two ends of the long hole are arc-shaped, the sliding part is a cylindrical shaft, and the outer contour of the sliding part along the axial direction is matched with the arc shapes of the two ends of the long hole, so that the sliding part can move to the end part of the long hole, and the stress concentration can be reduced due to the arc-shaped arrangement, and the reliability of the structure is improved.
