By utilizing the frequency correlation of two-photon states produced via spontaneous parametric down conversion, the working principle of a remote spectrometer is demonstrated. With the help of a local scanning monochromator, the spectral transmission function of an optical element (or atmosphere) at remote locations can be characterized for wide range of wavelengths with expected high resolution. © 2003 American Institute of Physics.
