Compact, Rugged and Low-Cost Atmospheric Ozone DIAL Transmitter

Completed Technology Project

Project Description

Final Summary Chart Image
Real-time, high-frequency measurements of atmospheric ozone are becoming increasingly important to understand the impact of ozone towards climate change, to monitor and understand depletion of the ozone layer, to further understand its role in atmospheric chemistry, and to assess its impact on human health and the productivity of agricultural crops. Expansions of tropospheric ozone measurement efforts, such as NASA?s TOLNet program, are critical to improve our understanding these effects. In response to this need, Bridger Photonics Inc proposes developing the most efficient, compact, rugged, low-power consumption and cost-effective UV ozone differential absorption lidar (DIAL) transmitter available. The proposed transmitter will enable widespread deployment of ozone DIAL systems capable of continuous range-resolved atmospheric ozone measurements from ground-based and airborne platforms to advance NASA?s Earth science mission. To achieve this design goal, Bridger will apply innovations proven out during its Phase I effort and developed previously for its MIR series laser product. The overall project goal is to design, construct, and test an autonomous, production-grade prototype, two-wavelength ozone LIDAR transmitter. The proposed transmitter will enable state-of-the-art continuous ozone LIDAR measurements without the need for a skilled operator. It will also provide a long maintenance-free interval (> 2 years), and will cost under $200k per transmitter. Successful completion of this Phase II program will allow Bridger to demonstrate a simultaneous DIAL, brassboard transmitter with pulse energies >200 ?J in both DIAL wavelengths capable of autonomous operation, without degradation, for 3 months.
