Description
本发明涉及一种沿相机光轴方向移动靶标的方法及装置，属于光学成像系统领域。The invention relates to a method and a device for moving a target along the optical axis direction of a camera, belonging to the field of optical imaging systems.
相机是指集成了成像镜头和成像探测器的一类设备，其能够利用光学成像原理形成目标物体的影像并记录下来。随着光学成像技术的发展和应用需求的拓展，利用相机拍摄影像已经在人类的工业生产、日常生活、科学研究等各种活动中变得不可或缺。A camera refers to a type of device that integrates an imaging lens and an imaging detector, which can use the principle of optical imaging to form and record an image of a target object. With the development of optical imaging technology and the expansion of application requirements, the use of cameras to capture images has become indispensable in various human activities such as industrial production, daily life, and scientific research.
在众多的相机应用中，沿相机的光轴方向精确地前后移动成像目标是一种常见需求；例如在测试相机的成像景深时，需要将分辨率靶标沿相机的光轴方向前后移动，观察清晰成像的距离范围；又例如将特定图案的靶标沿相机光轴方向前后移动，相机拍摄不同距离下的图像并估算成像点扩散函数；又例如在基于相位差法的相机成像波前传感中，需要沿光轴方向移动成像靶标，使相机拍摄不同离焦下的靶标图像；以上应用对移动距离和移动方向的精度要求很高；而在实际场景中，靶标运动方向与相机光轴方向不可避免地存在夹角，而夹角过大会给计算带来很大的误差，甚至可能导致计算失效；所以，为了提高计算精度，精确地沿相机光轴方向前后移动靶标是非常必要的。In many camera applications, it is a common requirement to accurately move the imaging target forward and backward along the optical axis of the camera; The distance range of imaging; another example is to move a target with a specific pattern back and forth along the optical axis of the camera, the camera captures images at different distances and estimate the imaging point spread function; another example is in the camera imaging wavefront sensor based on the phase difference method, It is necessary to move the imaging target along the direction of the optical axis so that the camera can capture target images under different defocusses; the above applications have high requirements for the accuracy of the moving distance and moving direction; in actual scenes, the moving direction of the target and the direction of the optical axis of the camera are unavoidable There is an included angle between the ground and the ground, and if the included angle is too large, it will cause a large error in the calculation, and may even cause the calculation to fail; therefore, in order to improve the calculation accuracy, it is very necessary to accurately move the target forward and backward along the optical axis of the camera.
上文所谓光轴，是指通过光学系统所有表面曲率中心的一条直线；若是轴对称光学系统，光轴是公共的旋转轴。对于普通相机而言，理论上光轴通过相机探测器靶面中心。沿光轴方向移动靶标，难点在于光轴并不是一根真实存在的线，而是从概念出发虚构的线，所以无法找到实际参考基准，即使勉强以相机的某些边线作为基准，误差也很大，不能满足高精度应用需求。The so-called optical axis above refers to a straight line passing through the centers of curvature of all surfaces of the optical system; in the case of an axisymmetric optical system, the optical axis is the common axis of rotation. For ordinary cameras, theoretically, the optical axis passes through the center of the camera detector target surface. The difficulty of moving the target along the optical axis is that the optical axis is not a real line, but a fictitious line based on the concept, so it is impossible to find the actual reference. Even if some edges of the camera are used as the reference, the error is very large. Large, can not meet the high-precision application requirements.
现有的高精度装配光轴与导轨移动轴匹配的装置，将可移动导轨固定到光学平台上，再将光轴配准系统粗安装到可移动导轨上，将电子内调焦系统安到五维调节架上，然后用五维调节架调节电子调焦系统的位置，使电子内调焦系统与光轴配准系统在同一水平线上；再将平面镜放置在光轴配准系统上，反复调节五维调整架方位俯仰使返回的十字叉丝不动为止，固定测试装置；该方法步骤繁琐，而且无法应用于相机光轴与靶标移动轴匹配。The existing high-precision assembly device for matching the optical axis and the moving axis of the guide rail fixes the movable guide rail on the optical platform, then roughly installs the optical axis registration system on the movable guide rail, and installs the electronic internal focusing system to five on the three-dimensional adjustment frame, and then use the five-dimensional adjustment frame to adjust the position of the electronic focusing system, so that the electronic internal focusing system and the optical axis registration system are on the same horizontal line; then place the plane mirror on the optical axis registration system, and adjust repeatedly The azimuth and pitch of the five-dimensional adjustment frame makes the returning crosshair not move, and then fixes the test device; this method is cumbersome and cannot be applied to match the optical axis of the camera with the moving axis of the target.
一种高精度的保证靶标沿相机光轴方向移动的方法及装置亟待研发。A high-precision method and device for ensuring that the target moves along the optical axis of the camera needs to be developed urgently.

光学位移放大系统4对光源组合系统3直线运动中的光学位移进行放大和显示；具体的，光学位移放大系统主要由球面反射镜401、观察屏402组成。球面反射镜401的反射面对着光源组合系统3发射的细平行光束方向，将细平行光束反射出去，观察屏402放置在反射光束的传播路线上，反射光束在观察屏402上形成一个光点；通过靶标调整单元2调整光源组合系统3的水平位置和高度，使球面反射镜401的球心与细平行光束在同一高度上，而在水平方向错开一定距离。The optical displacement amplification system 4 amplifies and displays the optical displacement during the linear motion of the light source combination system 3 ; specifically, the optical displacement amplification system is mainly composed of a spherical reflector 401 and an observation screen 402 . The reflective surface of the spherical reflector 401 faces the direction of the thin parallel light beam emitted by the light source combination system 3, and reflects the thin parallel light beam. The observation screen 402 is placed on the propagation route of the reflected light beam, and the reflected light beam forms a light spot on the observation screen 402. ; Adjust the horizontal position and height of the light source combination system 3 through the target adjustment unit 2, so that the spherical center of the spherical mirror 401 and the thin parallel light beam are at the same height, but staggered by a certain distance in the horizontal direction.
如上所述的光学位移放大系统4的工作原理如附图5所示；图中，光源组合系统3在直线导轨101上某位置时，出射细光束设为a，a照射到球面反射镜401的反射面A处，反射光束与观察屏402的交点为A1；光源组合系统3沿直线导轨101平移到另一位置时，出射细光束设为b，b照射到球面反射镜401的反射面B处，该反射光束与观察屏402的交点为B1；因为光源组合系统3只是前后平移，所以光束方向不变，a//b；但是因为光束方向与沿直线导轨101平移方向有夹角
，所以a和b有一个位移d；d正比于夹角
；由于
比较小，所以d也比较小，直接放置观察屏402不易区分位移d；本实施例中，利用球面反射镜401的光线反射，通过反射光束与观察屏402的交点位置能够对位移d放大，如图中A1和B1所示；通过合理设计相关参数例如球面半径、球面与观察屏的距离等，能够轻松地将光学位移放大几十倍、几百倍甚至上千倍，并在观察屏402显示。当光源组合系统3沿直线导轨101直线平移时，通过观察观察屏402上光点的位移轨迹，即可对光束方向与光源组合系统3运动方向的夹角大小进行评估。

When the light source combination system 3 linearly translates along the linear guide rail 101 , by observing the displacement trajectory of the light spot on the observation screen 402 , the angle between the light beam direction and the movement direction of the light source combination system 3 can be evaluated.
所述相机组件，包括：相机5和相机调整单元6；其中，相机5设置在调整姿态后的所述光源组合系统3的输出端，用于将所述细平行光束直接输入所述相机中形成光斑；相机调整单元6与所述相机5可拆卸的连接，用于调整所述相机的姿态且使所述光斑位于所述相机形成的图像的中心；优选的，相机调整单元6对安装在其上的相机5的位置和姿态进行调整。相机调整单元6可以实现平移、俯仰、旋转等多自由度调整。相机调整单元6带固定结构，能够固定相机5；相机调整单元6带锁紧结构，调整姿态合适后，能够锁紧相机5。The camera assembly includes: a camera 5 and a camera adjustment unit 6; wherein the camera 5 is arranged at the output end of the light source combination system 3 after the posture is adjusted, and is used to directly input the thin parallel light beam into the camera to form Light spot; the camera adjustment unit 6 is detachably connected with the camera 5, and is used to adjust the attitude of the camera and make the light spot at the center of the image formed by the camera; preferably, the camera adjustment unit 6 is mounted on its Adjust the position and attitude of the camera 5. The camera adjustment unit 6 can realize multi-degree-of-freedom adjustments such as translation, pitch, and rotation. The camera adjustment unit 6 has a fixing structure, which can fix the camera 5; the camera adjustment unit 6 has a locking structure, which can lock the camera 5 after the posture is adjusted properly.
总之，本实施例中的装置，通过直线导轨101、底座102、靶标调整单元2、相机调整单元6实现沿相机光轴方向移动成像靶标，而光源组合系统3、光学位移放大系统4则用于辅助调整，使靶标运动方向平行于相机光轴方向；相机调整单元6对安装在其上的相机5的位置和姿态进行调整；光源组合系统3出射平行细光束，球面反射镜401和观察屏402组成光学位移放大系统，对光束方向和光源组合系统3运动方向不一致引起的光学位移进行放大和显示，有助于精确调整光源组合系统3的姿态。In short, the device in this embodiment moves the imaging target along the optical axis of the camera through the linear guide rail 101, the base 102, the target adjustment unit 2, and the camera adjustment unit 6, while the light source combination system 3 and the optical displacement amplification system 4 are used for Auxiliary adjustment to make the moving direction of the target parallel to the optical axis of the camera; the camera adjustment unit 6 adjusts the position and attitude of the camera 5 installed on it; the light source combination system 3 emits parallel thin beams, the spherical mirror 401 and the observation screen 402 An optical displacement amplification system is formed to amplify and display the optical displacement caused by the inconsistency between the direction of the light beam and the movement direction of the light source combination system 3 , which helps to accurately adjust the attitude of the light source combination system 3 .
