Time-domain terahertz hyperspectral imager

The utility model discloses a time-domain terahertz hyperspectral imager which comprises a time-domain terahertz hyperspectral imager body, an L-shaped fixing plate is embedded in the time-domain terahertz hyperspectral imager body, and a moving mechanism is installed between the L-shaped fixing plate and the inner wall of the time-domain terahertz hyperspectral imager body. Limiting grooves are formed in the two sides of the top end of the L-shaped fixing plate. An installed servo motor B rotates to drive a lead screw to rotate, the lead screw rotates to drive a sliding block to move, the sliding block moves to drive a sampling light beam strip to move in a reciprocating mode, through the reciprocating motion of the sampling light beam strip, comprehensive sampling of a sampling object is facilitated, the sampling integrity is guaranteed, a limiting block slides in a limiting groove, and therefore the sampling object can be accurately sampled. The distance between the two U-shaped frames is conveniently adju
