Reflective ghost imaging through turbulence
WebGet your Flying Weather Forecast before and during your flight - receive real time turbulence reports and discover where turbulence has been reported by aircraft currently in-flight. … WebCompared to the necessary light of short wavelength in previous ghost imaging, the use of longer wavelength light is demonstrated to bring about ghost images with higher spatial resolution, in strong atmospheric turbulence. Non-degenerate wavelength computational ghost imaging with thermal light source is studied theoretically and experimentally.

WebThe influence of the incident angle on the imaging quality of reflective ghost imaging is investigated through atmospheric turbulence. It is shown that under mediate turbulence, … WebMay 30, 2024 · The ghost imaging system in transparent liquid is shown in Fig. 1. The pseudothermal source is prepared by illuminating a pulsed Nd:YAG laser into a slowly rotating ground glass. A nonpolarizing beam splitter (BS) splits the incident thermal light beam into two beams.
WebLimited by long acquisition time of 2D ghost imaging, current ghost imaging systems are so far inapplicable for dynamic scenes. However, it’s been demonstrated that nature images are spatiotemporally redundant and the redundancy is scene dependent. WebJan 14, 2012 · This paper presents an overview of the physics of ghost imaging. It clarifies and unites two disparate interpretations of pseudothermal ghost imaging—two-photon …
