Optic field
WebFree-space electro-optic field sensors have be used to characterize the temporal, spectral, and spatial distribution of freely propagating terahertz beams (THz beams). This detection system, which uses an electro-optic crystal sensor, provides diffraction-limited spatial resolution, femtosecond temporal resolution, DC-THz spectral bandwidth, and a sub … Weboptics, and thus can operate with plastic (birefrin-gent) specimen substrates [10]. Therefore, filtering in the Fourier plane of the image field with a sinusoi-dal amplitude mask gives an …
