Abstract 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.

傅里叶时间鬼成像

摘要 在传统的时域重影成像系统中，在恢复时域信号时需要采用傅里叶变换来获取信号的光谱信息。在本文中，一种新技术结合了时域鬼像成像和傅里叶变换的特点，利用具有确定正弦和余弦分布的时变光强，根据信号的光谱信息直接获取信号的光谱信息。检测强度信息。实验结果证明了所提出方法的有效性。傅立叶-时间重影成像结合了时域重影成像和傅立叶频谱分析的优点，在微弱和瞬时信号采集和分析领域具有重要的应用和科学价值。
