Abstract
A method and a system for single-shot multi-frame ultrafast terahertz imaging of a scene, the method comprising generating a pump beam and a probe beam: generating a THz beam from the pump beam and passing the THz beam through the scene: multiplexing the probe beam in the time domain and in the spatial-frequency domain, yielding a multiplexed probe beam; detecting a THz beam passing through the scene; guiding the multiplexed probe beam to a THz detection crystal and converting the multiplexed probe beam into mutually orthogonal linear polarized beams; guiding the mutually orthogonal linear polarized beams to a camera; and recovering frames of the scene from multiplexed images acquired by the camera.
