An industrially hardened terahertz electromagnetic transmitter and receiver
module (29) is disclosed. The electromagnetic wave module has an optic
(30) which relays an optical pulse from the delivery fiber (32) to the
terahertz device. The relay optic (30) allows for a greatly reduced
optical spot size as compared to the output of the optical fiber. Thus,
the sensitivity of the overall system is enhanced by improving the
efficiency of the terahertz device. The relay optic (30) allows the small
spot of light to be aligned to the electromagnetic transmitter or receiver
with sub-micron precision.
