摘要： An apparatus for the imaging of gaseous fluid motion is disclosed. The apparatus includes a sub-nanosecond pulsed laser. The sub-nanosecond pulsed laser is configured to cause a particle species to fragment and for the recombining fragments subsequently to fluoresce. The apparatus also includes a gaseous fluid comprised of particle species. The apparatus also includes a time gated camera. The time gated camera configured to capture at least one image of the fluorescence from the recombining particle fragment species displaced after a specific time lapse following the laser pulse. Additionally, a fluid velocity can be calculated from a comparison of the image of the displaced particle species to an initial reference position and the time lapse. A Femtosecond Laser Electronic Excitation Tagging (FLEET) method of using the disclosed apparatus is also disclosed.

摘要： Systems and methods for lasing molecular gases, and systems and methods of detecting molecular species are provided. The systems and methods can include the use of an excitation laser tuned to a wavelength associated with oxygen or nitrogen. The lasing can occur in both the forward and reverse directions relative to the excitation laser beam. Reverse lasing can provide a laser beam that propagates back toward the excitation laser source, and can provide a method for remote sampling of molecular species contained in the air. For example, systems and methods of detecting a molecular species of interest can be achieved by using the properties of the backward or forward propagating air laser to indicate a change in a pulse from the source of laser pulses caused by a modulation laser tuned to interact with the molecular species of interest.

摘要： A method and apparatus for remotely monitoring properties of gases and plasmas is disclosed. A laser beam is focused at a desired region within a gas or plasma to be analyzed, generating an ionized sample region in the gas or plasma. A beam of microwave radiation is directed toward the ionized sample region, and a portion of the microwave radiation is scattered by the ionized sample region and Doppler-shifted in frequency. The scattered, frequency-shifted microwave radiation is received by a microwave receiver, and is processed by a microwave detection system to determine properties of the gas or plasma, including velocities, temperatures, concentrations of molecular species, and other properties of the gas or plasma.

摘要： Systems and methods for controlling flow with electrical pulses are disclosed. An aircraft system in accordance with one embodiment includes an aerodynamic body having a flow surface exposed to an adjacent air stream, and a flow control assembly that includes a first electrode positioned at least proximate to the flow surface and a second electrode positioned proximate to and spaced apart from the first electrode. A dielectric material can be positioned between the first and second electrodes, and a controller can be coupled to at least one of the electrodes, with the controller programmed with instructions to direct air-ionizing pulses to the electrode, and provide a generally steady-state signal to the electrode during intervals between the pulses.

摘要： First and second relatively high power laser beams are directed into a volume enclosing a flow field of molecules of a molecular species. The beams are focussed to form an overlapping region of the beams in the flow field, for tagging a portion of the associated molecules by driving them into their first vibrational state by stimulated Raman pumping. A high intensity beam of light is directed into the flow field proximate the overlap region for intercepting the tagged molecules, and causing them to fluoresce, thereby permitting their displacement to be measured through observation thereof, for determining the velocity of the associated molecules and flow field.
