What is a DGTS detector

What is a DGTS detector?  DGTS detector or deuterated triglycine sulfate detector

Definition: A very sensitive room-temperature detector for mid-infrared range measurements that employs temperature-sensitive ferroelectric crystals of deuterated triglycine sulfate. As the temperature and hence polarisability of the crystals changes (due to the absorption of infrared radiation) a charge is generated which is detected by two parallel electrodes. The deuterated form of the crystals are used because they have a higher Curie point.

Synonyms:

  • deuterated-triglycine sulfate (DTGS) detector
  • DTGS detector
