The superposition of Laguerre-Gaussian guided into and scattered by a particle in a rotated fluid allows the detection of the rotational of the fluid. The presented system allows for virtually real-time determination of vorticity characterization in a fluid. The system allows the direct measurements of fluid flow vorticity using a spatially shaped beam with a superposition of Laguerre-Gaussian modes that reports on the rotational Doppler shift from microparticles intersecting the beam focus.

Laser system for measuring fluid dynamics

The performance of an internal combustion engine is optimized utilizing an electrically controlled driver which is located relative to the intake port to excite the intake charge at a selected frequency, duration and power level which depends on the engine operating condition. The purpose of this excitation is to control combustion by optimizing large scale recirculation patterns of the intake charge within the combustion chamber. In particular, this device will provide the effect of optimizing volumetric efficiency at wide open throttle and minimize fuel consumption and emissions at part throttle. An electronic engine controller varies the operation of the drive device as a function of engine operating conditions. The driver excites the intake charge at a frequency of about 5 to 1000 times of the engine speed.
