The beam profile and wavefront of the THz beam at focus are electro-optically characterized toward the realization of a real-time THz camera. A peak dynamic range of ~37 dB/ square root of Hz is achieved with single-pixel detection.enterahertz imagingelectro-optical materialsphotodiode621journal article
