THz imaging and radiometric measurements using a microbolometer-based camera

A THz VOx-based 160×120 microbolometer FPA camera with 52 μm pixel pitch has been developed at INO. Radiometric NEP values have been measured at different wavelengths. Real-time video-rate reflectance imaging using large beam area from a high-power FIR optically pumped THz laser has been also performed, demonstrating high sensitivity for stand alone applications.
