红外光子 meaning in English
infra-red photon
Examples
- One of the key techniques is the detection of near infrared ( 1310nm and 1550nm ) . because the quantum key is transmitted by one photon , and 1310nm and 1550nm infrared are the lost loss wavelength in fiber . we can detect the visible light now , but it is difficult to detect the near infrared because of its low energy
量子通信的关键技术之一就是红外( 1310nm 、 1550nm )单光子探测,这是因为光量子密钥传输是采用单个光子来实现的, 1 . 3微米和1 . 5微米是现在所使用的光纤通信中损耗最小的波长,现有成熟的单光子探测器工作波长都是在可见光波段,而红外光子因为能量小,信号非常微弱,极易被噪声淹没,因而非常难探测到。
