法国SFENA公司研制成功利用最新电光技术和数字技术的直升飞机瞄准具。该液晶瞄准具全部采用固体电路,用28伏直流电源供电,功率消耗低于50瓦,重量低于7公斤(15.4磅),视野为300 mrads。瞄准具安装在座舱盖边框上,正好处在飞行员眼睛的正前方。该装置包括一个亮度可调的白色光源,一个夜间观测望远镜上用的绿色滤光镜,一块由符号发生器直接控制的液晶显示板(符号发生器安装在设备的机壳内),
France SFENA company successfully developed using the latest electro-optical technology and digital technology helicopter sights. Powered by a 28 VDC power supply, all solid-state sight devices use less than 50 watts of power, weigh less than 7 kilograms (15.4 pounds) and have a field of view of 300 mrads. The sights are mounted on the canopy cover just in front of the pilot’s eyes. The device includes a white light source with adjustable brightness, a green filter for night-time observation binoculars, a liquid crystal display panel directly controlled by the symbol generator (the symbol generator is mounted in the cabinet of the device)
