Ghost imaging obtains an image of an amplitude/phase object by spatial correlation between two separated light beams.In ghost imaging, two detectors are used in a counter-intuitive way.One is a multi-pixel detector that does not view the object in reference arm, and the other one is a single-pixel detector that does view the object but only Cyclist Accessories - Triathlon - Womens Triathlon record the total light power in object arm.Neither detector could recovery the object independently, but spatial correlation from two detectors allows the reconstruction of a ghost image of the object.

Here for the first time we present ghost network analyzer for obtaining frequency properties of a target.Interestingly, this novel technique proves insensitive to the distortion introduced by nonlinear devices, while conventional frequency-domain measurement modalities such as network analyzer Bar Cart can hardly work properly with distortion.The proposed technique provides a breakthrough method for distortion-free dynamic frequency response analysis.
