These types of pyroelectric detectors are optimized for application in THz region. The detectors are small, have a large active area and a short response time.
The basic principle is the absorption of radiation pulses from a pulsed or per chopper modulated cw radiation source on the absorbing layer. In combination with a low-noise current amplifier it is possible to detect the power of the radiation source.
The THz-Trap has a special build up out of 3 sensor elements which allows to absorbing nearly 100% of the irradiated wavlength as a result of multi absorption und -reflection.
