Temporal Ghost Imaging by Means of Fourier Spectrum Acquisition
Ghost imaging is a fascinating framework which constructs the image of an object by correlating measurements between received beams and reference beams, none of which carries the structure information of the object independently.

| description | Ghost imaging is a fascinating framework which constructs the image of an object by correlating measurements between received beams and reference beams, none of which carries the structure information of the object independently. Recently, by taking into account spacetime duality in optics, computational temporal ghost imaging has attracted attention. Here, we propose a novel Fourier temporal ghost imaging (FTGI) scheme to achieve single-shot nonreproducible temporal signals. By sinusoidal coded modulation, ghost images are obtained and recovered by applying Fourier transformation. For demonstration, non-repeating events are detected with single-shot exposure architecture. It is shown in experimental results that the peak signal-to-noise ratio (PSNR) of FTGI is significantly better (13 dB increase) than traditional temporal ghost imaging in the same condition. In addition, by using the obvious physical meaning of the Fourier spectrum, we show some potential applications of FTGI, such as frequency division multiplexing demodulation in the visible light communications. |
