OPTOGAMA: Infrared (IR) viewers 紅外(IR)觀察儀
數(shù)字版本的紅外觀察儀(DIG 系列)基于多光子吸收(MPA)現(xiàn)象,此時(shí)激光波長超出了硅材料的線性光譜檢測范圍。此外,光電子過程需要對(duì)噪聲進(jìn)行空間和時(shí)間濾波,以增強(qiáng) 1.1 微米以上光譜的紅外光子的可視化效果。通過逐像素調(diào)整增益,可實(shí)現(xiàn)高達(dá) 1.7 微米的成像。
基于高級(jí)圖像轉(zhuǎn)換器的高性能圖像轉(zhuǎn)換紅外觀察儀(IC 系列),旨在觀察 350 – 2000 納米光譜范圍內(nèi)紅外激光、發(fā)光二極管(LED)、染料及其他紅外光源的間接輻射。紅外觀察儀基于第一代高級(jí)圖像轉(zhuǎn)換器,該轉(zhuǎn)換器具有靜電聚焦系統(tǒng)、氧濃度增加的 S – 1 + 光電陰極以及在 550 納米處發(fā)光最強(qiáng)的 P – 20 型屏幕。紅外觀察儀將選定物體發(fā)射或反射的光聚焦到成像管中,在那里生成電子圖像。通電時(shí),會(huì)產(chǎn)生 16 – 18 千伏的電壓,將電子圖像加速射向輸出端的磷光屏。通過可調(diào)節(jié)目鏡可觀察到綠色熒光輸出(550 納米)。
