Abstract

The working principle of the remote spectrometer was demonstrated utilizing the frequency correlation of two photon states produced via spontaneous parametric downconversion (SPDC). The spectral transmission function of an optical element at remote locations could be characterized for wide range of wavelengths with expected high resolution. The spectral function of the remote spectral filter was obtained by measuring the rate of coincidence counts at each wavelegths defined by the monochromators. The results show that the remote measurements agree with the standard laboratory classical spectral transmissivity.
