Delta-Sigma Modulated Photodetection Method to Reduce Laser Power, Year 1
Project Description
The use of mixed-signal processing techniques implemented on integrated circuitry allows the detection of pico-watt optical signals. By using ratiometric methods, a real-time reading of differential absorption lidar information may be obtained. The system provides correlated measures between differing photodetector types allowing direct ratio measures between different species of absorbing materials.

Anticipated Benefits
The oil/gas industry may have use in remote detection of leaking gases. There may be a possibility for use in chemical weapons detection. Portable methane detection for use in coal mines or other such environments seems feasible.
