In this paper, the research intention and design principle of CY-1R night vision helmet are explained which fills
the gaps in active-passive combined night vision field in our country. The structure, composition, mechanism and
overall performance of the goggle are analyzed. It is a new type device consisting of laser illuminator system,
special optical system and high performance low-level-light intensifier. Based on these characteristics, the
sensitivity of the system is high and the image observed is very clear. Taking advantage of it, we can complete the
military operation under any atrocious weather conditions.
