Popis:	Milliwatt average power terahertz quantum cascade lasers (THz-QCLs) combined with microbolometer focal plane array cameras allow for acquisition rates on the order of 1×10 6 pixels/s. This system enables real-time imaging in transmission and reflection modes with signal to noise ratios of >25 dB per pixel. While these system allow rapid imaging for fairly transparent samples, signal to noise ratios of > 90 dB can be achieved with single element detectors where the samples are more opaque or require higher SNR. Systems using LongWave's terahertz QCLs and single/multi-element detectors will be presented.
