Confocal THz Laser Microscope
in: Journal of Infrared Millimeter and Terahertz Waves (2010)
We transfer the principle of the optical confocal microscope to a far-field THz imaging system based on an optically pumped gas laser emitting radiation at 2.52 THz. This results in a contrast enhancement. To illustrate the image quality improvement, we show THz images of different objects taken with the suggested scheme and compare them to images taken with other systems.
