Terahertz image dataset
WebAn illumination beam with a subwavelength waist and extended focal depth is ideal for terahertz computed tomography. In this paper, a binary terahertz super-oscillatory lens is proposed with a full width at half-maximum of 0.97λ, a focal length of 48λ, a focal depth of 25λ, and a numerical aperture of 0.24. Webterahertz: [noun] a unit of frequency equal to one billion hertz.
