SBIR-STTR Award

In this SBIR project Boston Applied Technologies, Inc. (BATi) proposes a unique optical imager for remote gas sensing. Tunable filters based on electro-optic effect have shown great potential in detecting gas concentration through obtaining its absorption spectrum. The core of the proposed imager is a high speed electro-optic tunable filter based on patented OptoCeramic® material developed by BATi. This compact passive imager covers a large portion of mid-wave infrared. An innovative technical approach is proposed to achieve narrow bandwidth at the same time. The successful combination of wide tuning range and sharp passing bands makes the image have excellent ability of detecting critical gas species such as carbon dioxide, carbon monoxide, methane and water vapor simultaneously at high precision. The imager also features high speed, big aperture, large angle of view, robust, light weight, and low cost.
