Effect of different temporal light fields on compressive temporal ghost imaging reconstruction

In this paper, we study the effect of different temporal light field patterns on compressive temporal ghost imaging. Wavelength division multiplexing technology is used for temporal ghost imaging to improve imaging efficiency. The applicability, robustness, and reconstruction performance of different temporal light fields are verified on the basis of research on the temporal ghost imaging mechanism. Simulation shows that Hadamard temporal light field pattern has better reconstruction effect and anti-noise ability than other light field patterns, and applies to different kinds of signals. (letter)
