The core component of infrared digital night vision is the image sensor, which determines the final image effect of the light filtered by the object mirror. The night vision instrument is created in order to clearly observe the environment in the dark. It can clearly understand the goals in the environment in the microman and all black environments, that is, the core performance of the night vision itself. Judging from the upgrade stage of image sensors, it has now been upgraded to the four generations in the field of civil digital night vision instruments. At the same time, the auxiliary functions of the digital night vision instrument have also increased significantly, such as remote control functions. In other words, the four -generation digital night vision instrument belongs to the latest generation of digital night vision instruments, so how is the digital night vision instrument in the conventional sense? Here, the first-line brand upgraded OrPHA Olfa DB550+and another domestic brand Cookie Binox-Basic for control evaluation. Olfa DB550+belongs to the night vision instrument that adopts the four generations of low-illuminated image sensors, which is the four-generation infrared digital night vision in this article; Cookie Binox-Basic is cheap. Accept, the digital night vision instrument belongs to the three generations and below.
The Aurfa DB550+and Cookie Binox-BASIC are relatively brisk and easy to carry, but Olfa products feel more solid, and can adopt a variety of power supply, such as charging batteries, charging treasures, DC power, etc.; Cookie Binox -Basic weight is lighter. Movies use common No. 5 dry batteries, and there are no other power methods available. In terms of power, it is a point that cannot be ignored in many use, and determines the length of the use time. It is obvious during the evaluation process. Some high -power use projects such as the infrared detection mode consume a lot of power at night. A variety of power supply methods of Olfa are more suitable for long -term outdoor operations.
The core use of the digital night vision instrument is the night viewing experience. Both are both double -eyed and double -tube design. The experience of use is good, which is in line with the habit of watching our normal eyes. The double -eyed and double tube are mainly viewed through the imaging screen inside the digital night vision instrument. Olfa’s screen is larger in rectangular, wider field of vision, and cookie’s products are mainly square vision. In the process of using Olfa DB550+, because it has a 5-30 times zoom, it will be far from the distance, and it can be zoomed in the focus; cookie’s product zoom is only 8 times the starting rate, the pixels are too low, zoomed in and shrink to watch the viewing Experience is average.
The viewing experience here generally means that after getting started, the starting rate of Cookie is too high to magnify, such as watching a tree. The larger range of things can not be seen; the visual field of the Orfa DB550+is wider, because the starting multiplier rate is low, you can see the relatively large -range close -range objects, and the color saturation in the conventional sunlight mode is better.
After entering the dark environment at night, the test conditions changed, and the two performed differently in the micro -light and full black environment. Olfa’s four -generation night vision instrument is obviously stronger for light capture, and has a enhanced version of infrared detection. Instead of seeing the things in all black and non -light, it is more clear. In the field of vision, there is a enhanced circular observation area; This enhanced observation function cookies are not available. Only the more conventional infrared vision is more clear than the ordinary natural light mode. In addition, after observing the same objects, the four -generation night vision instrument is stronger because of the sensitivity and capture ability of light, the imaging is clearer, and the color contrast is obvious, which is conducive to distinguishing the physical object. Non -fourth generation of cookies, the color of the background and prospects is more similar. Of course, there are many different functions, because the new four -generation digital night vision instrument, currently not only the upgrade of core components, but also upgrades of other functions, such as GPS, WIFI, remote control, compass, etc. These functions are also past. What the version of the digital night vision instrument does not have.
