Thz Applications

An infrared (IR) pyroelectric detector was investigated for terahertz (THz) detection using the principle of the terajet effect, which focuses the beam beyond the diffraction limit. The terahertz beam was coupled to the detector’s optical window through a two-wavelength-dimension dielectric cubic particle-lens based on the terajet effect. We experimentally demonstrate an enhancement of about 6 dB in the sensitivity under excitation of 0.2 THz without degradation of the noise equivalent power value. The results show that the proposed method could be applied to increase the sensitivity of various commercial IR sensors for THz applications that do not require modification of the internal structure, and it may apply also to acoustics and plasmonic detectors.

Gas Chamber

In this work, design method for fabricating optical gas chamber of infrared gas sensor was introduced in detail. IRL715 infrared source, PYS3228 pyroelectric detector with double filters and optical gas chamber were assembled into the optical gas chamber, and then the Nor-infrared (NDIR)gas sensor was produced. After tested in specific methane environment, the performance of optical gas chamber was verified. Meanwhile, optical gas chamber was processed with dustproof and waterproof measures. Experimental results show that response sensitivity of optical gas chamber is good.
