Adaptability Improvement of White Light Observation and Sighting Equipments in Plateau Snow Environment

The Military Representative Bureau of Chongqing Regional, Kunming 650032, China

摘要

摘要: 为解决白光观瞄装备在高原雪地、逆光等环境条件下观察瞄准效果不佳等问题，运用外置滤光镜、偏振光镜和遮光筒等技术，对白光观瞄装备开展适应性改进，充分考虑高原任务特点，合理进行人机工效设计，方便操作和携行，满足白光观瞄装备在高原地区各种环境条件下的使用需求。

Abstract: White light observation and sighting equipment exhibit a poor performance in regards to observing snow and backlighting conditions on plateaus. To address this, external filters, polarizing lenses, and shading tubes are used to improve the adaptability of the white light observation and sighting equipment by fully considering the characteristics of plateau tasks. Reasonable man–machine ergonomics designs, convenient operation, and portability allow meeting the needs of white light observation and sighting equipment under various environmental conditions in plateau areas.

表 1 滤光镜部分试验结果

Table 1. Partial test results of filter

The test project	Test results
Maintainability	The installation and removal time is 30 s
Interchangeability	The polarizing lens, the shading cylinder and the structure can be interchanged, and the function is normal
Continuous observation test in snow	Greater than 30 minutes
The angle at which the sun's rays can be shielded after the hood is installed	18°
Backlighting observation window time test	72 min
Target identification test	①When adding a polarizer on the sighting mirror, the angle of the polarizing can be adjusted to filter out the “glare” and the light intensity through the aim can be adjusted to achieve the comfortable effect of human eyes, and is suitable for long-term observation and aim under various lighting conditions ②Adding a yellow filter on sight can increase the contrast of the target and distinguish the personnel and equipment more clearly, especially suitable for use in the low light conditions such as mist ③The light-shading tube installed in front of the filter can effectively block the backlighting. With the filter, it is suitable for all kinds of intensity backlighting environment
High temperature operation	Proper operation
Low temperature operation	Proper operation
