Stand-alone compact diode laser sensor for airborne measurements

摘要

A new, near-infrared, diode laser based hygrometer, designed for operation in unmanned aerial vehicles, is presented. This instrument is designed to accurately and rapidly measure moisture from sea level to the lower stratosphere. It is compact, lightweight and requires very little power. All system control and data processing are accomplished using a stand-alone digital signal processor super- controller. The usefulness of this approach for atmospheric measurements as well as other industrial applications will be presented.
