INO (Canada) INO has leveraged its expertise in the development of uncooled microbolometer detectors for infrared imaging to produce terahertz (THz) imaging systems. Optimization of the sensitivity in the THz band has been accomplished by the addition of metamaterial-based absorbers to its microbolometer focal plane arrays. With the addition of custom THz lens objectives, INO now produces the IRXCAM-THz-384 camera, capable of imaging hidden objects for applications such as non-destructive testing, non-intrusive threat detection and see-through-the-wall imaging.
14:20 : Tunable Photonic Band Gap Materials for High Sensitivity Displacement Transduction in MEMS Inertial Sensors
Salvatore Baglio, Bruno Ando, Carlo Trigona
University of Catania (Italy) This paper deals with the synergic use of Photonic Band Gap (PBG) materials and Micro-Electro-Mechanical Systems. Stacked metal-dielectric PBG structures which include also one air gap are considered, changes induced in the air gap will affect the overall optical properties thus making the PBG mechanically tunable. Applications to MEMS inertial sensors are presented with particular emphasis on integrated Gyroscopes where the proposed approach allows for conjugating two diverging features as mechanical robustness and high sensitivity to very small displacements.
