Abstract: In this electric field vector detection method, an electro-optic crystal, where a (111) surface of an optical isotropic medium is cut out, is used as a terahertz wave detection element. The method includes: causing polarization of probe light of ultrashort pulsed light to be circular polarization; allowing the probe light having circular polarization to enter the terahertz wave detection element and probing the terahertz wave; modulating the probe light, having probed the terahertz wave, by a rotating analyzer and detecting the modulated probe light by a photodetector; performing lock-in detection of a detection signal from the photodetector by a lock-in detector using a frequency based on a rotational frequency of the rotating analyzer as a reference signal; and detecting an electric field vector of the terahertz wave based on a detection signal from the lock-in detector.

Abstract: Prism-coupling systems and methods for characterizing large depth-of-layer waveguides are disclosed. The systems and methods utilize a coupling prism having a coupling angle α having a maximum coupling angle αmax at which total internal reflection occurs. The prism angle α is in the range 0.81αmax≦α≦0.99αmax. This configuration causes the more spaced-apart lower-order mode lines to move closer together and the more tightly spaced higher-order mode lines to separate. The adjusted mode-line spacing allows for proper sampling at the detector of the otherwise tightly spaced mode lines. The mode-line spacings of the detected mode spectra are then corrected via post-processing. The corrected mode spectra are then processed to obtain at least one characteristic of the waveguide.

Abstract: There are disclosed a method and a system for non-contact control in a form of a polarization marker, a receiving device, and a microprocessor. In the polarization marker, beams are polarized with a customized cylinder polarizer, pass through a system of lenses and reflectors and are emitted into space, wherein the direction of the polarization vectors is axially symmetrical about the virtual axis of the polarization marker. The receiving device located in the working plane identifies the direction and position in space of the polarization marker in relation to the receiver, the results being interpreted by the microprocessor into control commands The receiving device consists of polarimeters spaced at a predetermined distance. The polarimeters identify the direction of the polarization vectors of incident beams from the polarization marker. Based on the data obtained from each polarimeter, the microprocessor calculates the direction and angles of site of the polarization marker.
