Abstract

In order to develop the remote Raman technology, we independently developed the gated-single-photon camera, and construct the Raman demonstration system by the gated-single-photon camera and low energy, high repeat frequency, sub-nanosecond plused laser. And we detect the Raman signal of chlorobenzene and potassium nitrate which is 0.5 meter away from the focal lens, and the signal is high ratio of signal to noise and easy to distinguish the material by the Raman fringerprint. In this article, we initially demonstrate the advantage and potential of gated-single-photon camera in remote Raman detection. The technique proposed in the article has strong application extensibility, and will be important in security-check and mineral survey, etc.
