Focal-plane micro-bolometer arrays for 0.5 THz spatial room-temperature imaging

The possibility of using commercial classical near-infrared (~30 THz) focal-plane micro-bolometer arrays in the sub-terahertz frequency range is studied. The real-time room-temperature pixilated detector imaging of a 0.5 THz (λ = 600 μm) spatial beam profile emitted from a backward-wave oscillator i...

Zusammenfassung:The possibility of using commercial classical near-infrared (~30 THz) focal-plane micro-bolometer arrays in the sub-terahertz frequency range is studied. The real-time room-temperature pixilated detector imaging of a 0.5 THz (λ = 600 μm) spatial beam profile emitted from a backward-wave oscillator is presented. The images with a signal-to-noise ratio of 5 are demonstrated, leading to an estimate of the noise equivalent power of 11 nW · Hz^sup -1/2^.
