| 摘 要： | 通过构建两个正交的光功率比值,以光子技术实施微波频率测量.首先,待测微波信号经外调制器加载到连续光源上,在单边带载波抑制调制下仅得到单个光边带;以光学梳状滤波器对其进行滤波处理,在输出端检测得到随微波频率增大而呈现余弦函数和正弦函数变化趋势的两个光功率;将这两个光功率与参考光功率进行比较后,进而得到余弦函数型和正弦函数...

| Abstract: | A photonic approach using two quadrature optical power ratios is proposed to peerform microwave frequency measurement.First,under the carrier-suppression and single-sideband modulation,a microwave signal is applied to modulate a cont;nuous-wave(CW) laser source,leading to the generation of a single sideband.,Then optical comb filters are adopted to process the sideband and two optical powers presenting sine-form and cosine-form distributions are detected as the microwave frequency increases.After comparing ... |
