Description: Using alternative methods of data processing based on mixed-signal integrated circuits allows an entire multi-channel optical detection-to-digital representation system to be built on a circuit platform of about 2 mm x 2mm. The goal is to present a dual-channel DIAL detection system to provide an integrated, correlated ratiometric measurement in a package that will fit on or near an optical focal plane.

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.
