Image resolution of infrared night vision device and digital night vision device Infrared night vision device is divided into 1 generation +, 2 generation +, quasi-3 generation, 4 generation, etc. The resolutions are different. For example, the resolutions of the 2nd generation + night vision devices in China are mostly between 50-60 line pairs, and they are still relatively high resolution. Even if infrared is added, the viewing distance is 100-200 meters. effective distance left and right. The ordinary CCD resolution of digital night vision devices is also above 50 line pairs. For example, the third-generation digital night vision devices use low-light high-definition CCD photoreceptors. The image brightness can be adjusted by the system, which can reach the second generation of infrared night vision devices + increase. A level like a tube level. Good infrared sensing ability, can reach an effective observation distance of more than 500 meters in total darkness
