Abstract :
Terahertz (THz) confocal scanning imaging is a combination of confocal scanning microscope and THz imaging, which could effectively improve the imaging resolution of the imaging system. The size of the confocal pinholes has a great influence on the system´s resolution. When the confocal pinholes are removed from the optical path, blurred imaging results are obtained. Lucy-Richardson method is applied to restore the blurred image and improve the image quality. The restoration result is compared with the imaging result when small pinholes were employed.
