Abstract :
We report the development of a terahertz imaging system based on the concept of compressive sensing. A spin disk with random patterns was used to modulate the terahertz beam, and terahertz image was subsequently reconstructed from the measured terahertz signals. We present experimental results obtained using both a BWO source at 0.14 THz and a thermal light source (blackbody radiation) covering both infrared and visible range.
