Binocular ranging night vision device that can be used both day and night
What does the ranging
暗視device we usually see look like?
There are three types of ranging night vision devices (or ranging thermal imagers) seen in the current night vision industry. These three types of distance measurement are the most common forms currently used by brands and manufacturers.
The first type of ranging night vision device is the reticle ranging algorithm. This can be said to be the most primitive form of ranging. Many brands of binocular ranging telescopes use this form. There is a cross reticle in the middle of the field of view seen from the eyepiece. According to the number of grids of each reticle The distance between the target object and the number of grids is used to determine an approximate value. For example, if there is an object at 1.36 meters, it will be 100 meters at the second grid of the differentiation board; if there is an object at 2.72 meters at the first grid, it will be 200 meters. The drawbacks of this type of night vision device ranging are obvious, and the accuracy of ranging is not high. This type of ranging is common in binoculars and a few early night vision products, and it is the most primitive way of night vision ranging.
