摘要：
An all-optical elecrical spectrum analyzer is demonstrated based on dual optical frequency combs and microwave photonic and it improves the resolutions to be 250 MHz over 10-GHz bandwidth, with the 1-KHz frame rate. The spectrum is directly obtained in the time domain, using as low as 10-MHz acquisition bandwidth, without any post-processing.
