Abstract: An apparatus and method of measuring free water, also known as undissolved water, in hydrocarbon fuel. A housing defines a chamber and is adapted to receive a fluorescein impregnated filter pad in the chamber between a UV light source and a light sensor. The filter pad is exposed to the fuel causing the free water to react with the fluorescein and is then placed within the chamber between the light source and sensor. The UV light strikes one side surface of the filter pad and excites the reacted fluorescein thereby causing light emitted from the UV light reacted fluorescein filter pad opposite side surface to strike the light sensor. An output from the light sensor is proportional to the fluorescein on the filter pad which reacted with free water and is used for providing an output value representative of the free water present in the hydrocarbon fuel.

Abstract: A laser device includes a light source that emits a source light having a first peak wavelength. A nonlinear optical component performs a frequency conversion process that converts the source light into output light having a second peak wavelength. A stabilization component minimizes a mismatch error constituting a difference between the first peak wavelength and a wavelength for which the frequency conversion process in the nonlinear optical component has a maximum value. The stabilization component may include a housing that is thermally conductive between the light source and the nonlinear optical component to minimize a temperature difference between the light source and the nonlinear optical component. The laser device may include a focusing optical component that focuses the source light to have a convergence half angle that is larger than a convergence half angle that gives maximum output power, thereby increasing an acceptable range of the mismatch error.

Abstract: An air-to-air background-oriented Schlieren system and method for measuring and rendering visible density changes in air that cause a refractive index change by an airborne vehicle. A sensor aircraft equipped with a high-speed visible spectrum camera travels at low airspeed on a predetermined route and on a level altitude over a background having consistent contrast and sunlight reflectivity. The target aircraft, traveling on the same predetermined route but at an altitude between the sensor aircraft and the ground (background) passes beneath the sensor aircraft. The camera on the sensor aircraft captures a series of images including a reference image immediately before the target aircraft enters the image frame followed by several data images as the target aircraft passes through the image frame. The data images are processed to calculate density gradients around the target aircraft. These density gradients include shockwaves, vortices, engine exhaust, and wakes.
