摘要：

In a traditional time-domain ghost imaging system, it is necessary to employ a Fourier transformation to obtain the spectral information of a signal when the time-domain signal is recovered. In this paper, a new technology combines the characteristics of time-domain ghost imaging and a Fourier transform and uses the time-varying light intensity, which has a definite sinusoidal and cosine distribution, to directly obtain the spectral information of the signal according to the detection intensity information. The experimental results demonstrate the effectiveness of the proposed method. Fourier-temporal ghost imaging combines the advantages of time domain ghost imaging and Fourier spectrum analysis has important applications and scientific value in the fields of weak and instantaneous signal acquisition and analysis.
