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.
