Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] The idea of the present invention is: combine the photon frequency shifting technology and the RF signal amplitude and phase extraction technology to realize the improvement of measurement accuracy; use the frequency shifting module with carrier and the optical detection module to realize the down-conversion function of fixed frequency, and convert the frequency-sweeping optical signal Converted to a fixed frequency radio frequency signal.
[0031] figure 1 It shows a structure of the optical device frequency response measurement system of the present invention. As shown in the figure, the measurement system includes a light source module, a frequency shift module with a carrier, an optical device to be tested, a light detection module, an amplitude and phase extraction module, and a control and The data processing module; the light source module outputs a sing...
