We propose and demonstrate single detector real-time line imaging with up to 1 mum resolution at 1 line/50ns capture rate. Experimentally we demonstrate real time line imaging of <25 mum particles and patterns such as fingerprints.
A real-time reflection/transmission imaging system is demonstrated using a 50-mW, 4.3-THz quantum cascade laser source in a closed-cycle cryorefrigerator, with a 240times320 pixel microbolometer detector. A signal-to-noise ratio of 340 is achieved with a 20-frame/sec acquisition rate.
