- Аннотация: Spectral measurements in the infrared (IR) optical range provide unique fingerprints of materialswhich are useful for material analysis, environmental sensing, and health diagnostics. Current IR spectroscopy techniques require the use of optical equipment suited for operation in the IR range, which faces challenges of inferior performance and high cost.Here we develop a spectroscopy technique, which allowsspectral measurements in the IR range using visible spectral range components. The technique is based on nonlinear interference of infrared and visible photons, produced via Spontaneous Parametric Down Conversion (SPDC). The intensity interference pattern for a visible photon depends on the phase of an IR photon, which travels through the media. This allows determining absorption coefficient and refractive index of the mediain the IRrange from the measurements of visible photons. The techniquecan substitute and/or complement conventional IRspectroscopy andrefractometrytechniques, as it uses well-developed optical components for the visible range
