术语 | fiber optics |
释义 | fiber optics 纤维光学,光纤技术 The technology of using thin glass filaments to transmit signals as pulses of light at frequencies of about 1014Hz. A filament acts as a wave guide for the light (reflecting it back and forth from the inside walls) allowing it to be transmitted around bends and over long distances with minimal loss. Existing applications include use as a cable replacement for connecting terminals and peripherals and for internal light paths in optical mark and character readers. 一种利用细玻璃纤维,以频率为1014Hz左右的光脉冲方式传输信号的技术。玻璃 纤维起光波导的作用(光波在其内壁上来回反射),使光波能沿弯曲路径以小的损耗长距离传 输。其目前的应用包括:代替电缆连接各种终端和外部设备,在光标及字符阅读器中用作内 部光路等。 |
