Terahertz imaging has found applications in many fields, to explore these applications we have built a coherent, transmission terahertz imaging system at 186 GHz. De-convolution algorithms were tested for improving the image’s resolution beyond the diffraction limit of the imaging system. Tested algorithms include the Wiener, Tikhonov, and Richardson-Lucy algorithms. Their performances are discussed and compared in this paper. Experimental results have demonstrated that coherent de-convolution algorithms are capable of improving the resolution of images formed with this imaging system.
