Infrared Metrology with Visible Light (по результатам проекта РФФИ 19-52-80034 БРИКС_т «Многофотонные высокоразмерные состояния света для задач квантовой информации»)

Infrared (IR) optical range is important for material characterization and sensing. The IR optical metrology is widely used in petrochemical, pharma, biomedical, homeland security, and other areas. Even though there are well-developed conventional methods for IR metrology, the remaining challenges are associated with high cost, low efficiency and regulatory requirements for IR light sources and detectors. To mitigate these issues we are developing new quantum-enabled techniques which allow us retrieving properties of materials in the IR range from the measurements of visible range photons.
