本发明属于激光测距技术领域，更具体的说是涉及一种正像系统及双筒激光测距望远镜。The invention belongs to the technical field of laser ranging, and more particularly relates to an erect imaging system and a binocular laser ranging telescope.
背景技术Background technique
测距仪是利用光、声音、电磁波的反射、干涉等特性，而设计的用于长度、距离测量的仪器。新型测距仪在长度测量的基础上，可以利用长度测量结果，对待测目标的面积、周长、体积、质量等其他参数进行科学计算，在工程应用、GIS调查、军事等领域都有很广的应用范围。A rangefinder is an instrument designed to measure length and distance by utilizing the reflection and interference characteristics of light, sound, and electromagnetic waves. On the basis of length measurement, the new rangefinder can use the length measurement results to scientifically calculate the area, perimeter, volume, mass and other parameters of the target to be measured. It is widely used in engineering applications, GIS surveys, military and other fields. scope of application.
测距望远镜为测距仪的一个重要分支，目前，激光测距望远镜的激光光路与可见光光路被分为两条互不相关的光路，使望远镜只能作为激光测距的瞄准器，不能在观察的同时进行测距。其原因是：所测得的距离不能显示在望远镜视场中，从而给用户带来诸多不便。同时，产品实现观察和测距的光学组件各自独立，形同搭积木式的组合，导致望远镜产品体积增大，重量加重，不便于携带，也不便于操作。The ranging telescope is an important branch of the rangefinder. At present, the laser light path and the visible light path of the laser ranging telescope are divided into two independent light paths, so that the telescope can only be used as the sight of the laser ranging, and cannot be used for observation. while measuring the distance. The reason for this is that the measured distance cannot be displayed in the field of view of the telescope, causing a lot of inconvenience to the user. At the same time, the optical components of the product for observation and ranging are independent of each other, which is like a combination of building blocks, resulting in increased volume and weight of the telescope product, which is inconvenient to carry and operate.
因此，如何提供一种正像系统及双筒激光测距望远镜成为了本领域技术人员亟需解决的问题。Therefore, how to provide an erecting system and a binocular laser ranging telescope has become an urgent problem to be solved by those skilled in the art.
