IR Metrology with Visible Light
IR instruments are indispensable tools for material analysis, environmental sensing, and homeland security. Through decades of development and commercialization, one common and significant limitation has been the weak efficiency of IR optical devices compared to their visible counterparts. IR components such as light sources, photodetectors, and cameras are also bulkier and costlier. A new approach to IR metrology, however, uses common optical components for the visible range.
