Removal of Microcystis aeruginosa by ultrasound .

2019-9-1 · The efficacy of ultrasonic irradiation for removal of Microcystis aeruginosa and release of algal organic matter (AOM) was investigated under different ultrasound conditions, including ultrasonic frequency, power density, and time. Laboratory results suggested that the ultrasonic efficiency and the release of AOM were influenced by frequency, power density, and time.

2020-1-6 · But the image quality can be degraded when the wavefront root mean square (RMS) value at the target plane, caused by high-order atmosphere turbulence, exceeds lambda/20. Beam emitted from larger aperture becomes more susceptible to perturbing effect, thus forming lower-quality wavefront.

Application Handbook - KAMAN

Ultrasonic: Ultrasonic sensors operate on a principle similar to sonar by interpreting echoes of sound waves reflecting off a target. A high frequency sound wave is generated by the sensor and directed toward the target. By calculating the time interval between the sent and received signals, distance to the target is determined.
