Abstract: The invention discloses a method for realizing an arbitrary ultrasonic field. The method uses a pulsed laser generated by a pulsed laser machine, modulated into a specific two-dimensional or three-dimensional light field distribution by a phase-type spatial light modulator, and the specific distribution of light acts on photoacoustic media. Due to the photoacoustic effect, a sound field distribution corresponding to the light field will be generated in the photoacoustic medium. The sound field constitutes a two-dimensional or three-dimensional spatial sound source. The sound waves emitted by the sound source are transmitted through a certain distance. The expected ultrasonic field distribution can be formed on a surface or inside of samples. The invention can transform the coherent ultrasonic field distribution formed on the surface or inside of the target object, simply by adjusting the phase distribution diagram input to the spatial light modulator, which has great flexibility.

Abstract: Aspects described herein estimate the pressure difference across a hollow region arising from fluid flow within the hollow region, based on an imaged fluid flow. The method utilises a complete description of fluid mechanical behaviour to derive an estimate of relative pressure or pressure difference over arbitrary flow segments. The method uses the concept of a virtual or arbitrary velocity field in the analysis of the work-energy of the fluid flow. Furthermore, the method uses statistical analysis to derive the acquired flow as a mean field and a related covariance quantity and uses this statistical description in the evaluation of virtual work-energy of the fluid flow. This assessment of virtual work-energy of the fluid flow is then used to derive an estimate of the pressure difference across any two given points (relative pressure) in the hollow region.
