Golay detectors

Terahertz scanning Fabry-Perot interferometer (TSFPI) is designed for measuring wavelength and intensity of narrowband THz radiation. TSFPI may be used with pulsed as well as continuous sources of narrowband THz radiation.

The compact lock-in amplifier SU-1, developed by Tydex, is designed to amplify high-noise signals.

Electro-Optic detector (EOD) is intended for registration of the pulsed terahertz (THz) radiation. It is characterized by availability of integrated optics as well as built-in lock-in amplifier. The detector has the following functions: signal conditioning; automatic signal balance fine tuning on photo-detectors. Facility of mechanical delay circuit control by means of the proprietary software supplied with the EOD is envisaged. Application field of the device includes time-domain spectroscopy (TDS).

Thermoacoustic detector TAD-1 is intended for measurement and registration of the microwave band impulses having duration from 1 to 500 ns within the range of 3 ÷ 300 GHz. Its operation is based on the effect of acoustic signal generation when absorbing microwave impulses in the layered structure.
