High-speed 600-GHz-Band Terahertz Imaging System Using Polygon Mirror

Acquisition speed is the key for industrial applications with a terahertz (THz) imaging technique. A 600-GHz-band high-speed imaging system using a polygon mirror is presented for this requirement. The polygon mirror of 250-Hz scanning frequency and the linear motion stage of 0.5-m/s speed are employed for the 2D imaging. The effective scanning aperture, maximum imaging speed and the spatial resol...
