摘要
介绍了光相干探测在不同技术领域的应用。通过各类具体实例讨论了光通信系统采用光相干探测技术可以增大通信容量,提高信号传输质量,光传感系统采用该技术可以提高信号探测灵敏度和发展多种多样的光传感模式,以及信号处理系统采用该技术可以改善信号处理性能。
Some application techniques of optical coherent detection are discussed in this paper. It is explained by specific examples that adopting optical coherent detection technology, the capacity of communication can be enlarged in optical transmission, the detection sensitivity can be increased in optical sensors, and the performance can be improved in signal processing.
