Abstract:
Ultrasonic vibration measurement and the development of ultrasonic vibration sensors have a significant impact on underwater pattern detection, providing good support for the exploitation and usage of marine resources. Advanced digital signal processing algorithms improve mechanical displacement measurements using ultrasonic speed and pm-level interferometers in real-time. In recent years, developing digital algorithms and employing low-cost software-defined radio (SDR) software applied to communication systems and other general-purpose systems with flexible solutions are essential in modern i

Abstract:
The use of interferometry to observe objects in three-dimensional space requires a corresponding rank of the system of interferometric base vectors. The paper considers one of the ways to solve such a problem using the rotation of a 1D interferometer at an angle to the rotation axis This, with the exception of special cases of parallelism or perpendicularity of the axes, makes it possible to form a consecutive 3D interferometer. Using the rotation of the Earth, such an interferometer performs Radon transform of the angular structure of the spatial image when observing sources far beyond the si

Abstract:
In the present study, a Nd;YAG Laser (pulse type) was used to emit ultrasonic signals to a test material. In addition, a total ultrasonic investigation system was designed by adopting a Fabry-Perot interferometer, which receives ultrasonic signals without any contact. For non-destructive test SM45C, which contains some flaws was used as a test material. Because it is easy to align light beam in receiver, and the length of the light beam does not change much even if convex mirror leans towards one side, confocal Fabry-Perot interferometer, which has stable frequency, and PI control are used to

Abstract:
As a high-end medical technology, high-intensity focused ultrasound (HIFU) is widely used in cancer treatment and ultrasonic lithotripsy technology. The acoustic output level and safety of ultrasound treatments are closely related to the accuracy of sound pressure measurements. Heterodyne laser interferometry is applied to the measurement of ultrasonic pressure owing to its characteristics of non-contact, high precision, and traceability. However, the upper limit of sound pressure measurement is limited by the bandwidth of the interferometer. In this paper, a high-bandwidth heterodyne laser in

Abstract:
This paper presents a technique that employs a stroboscopic oblique-incidence interferometer to visualize the motion of a vibrating object with a rough surface. An oblique-incidence interferometer is well suited to the analysis of a rough surface and micro displacement because light-scattering is reduced when a surface is rough. However, when continuous light is used, the fringe pattern on the vibrating surface in the ultrasonic region can not be observed for the analysis of a micrometer resolution profile. To overcome this problem, pulsed light synchronized with a vibrating sample is employed

Abstract:
The prevalence of concrete and cement-based materials in the civil infrastructure plus the risk of failure makes structural health monitoring an important issue in the understanding of the complete life cycle of civil structures. Correspondingly, the field of nondestructive evaluation (NDE) has been maturing and now concentrates on the detection of flaws and defects, as well as material damage in early stages of degradation. This defect detection is typically usually done by looking at the impulse response of the medium in question such as a cement-based material. The impulse response of a sol

Abstract:
Surface mount devices (SMDs), such as flip chip packages and ball grid array (BGA) packages are gaining in popularity in microelectronics industry because they provide high density inputs/outputs, better electrical and thermal performance. However, these solder bump interconnections in SMDs are sandwiched between the silicon die and the substrate, which makes them challenging to be inspected. Current non-destructive solder bump inspection techniques like electrical testing, X-ray and acoustic microscopy have some application gaps. New solder bump inspection technique is urgently needed to fill

Abstract:
Recent theoretical and experimental studies in a wide range of applications (ultrasonics, underwater acoustics, seismicoe) have demonstrated that Green's functions (impulse responses) can be extracted from cross-correlation of diffuse fields using only passive sensors. The technique, whose validity is supported by a physical argument based on time-reversal invariance, effectively uses a correlation process between the point source and points located in the focal zone. Indeed, the coherent noise source distributions can be considered as a timereversal mirror and the cross-correlation operations

Laser ultrasonics is a nondestructive evaluation method which relies on both optics and ultrasonics. A short-pulse laser generates an ultrasonic wave into the material to be inspected, and a long-pulse laser, coupled to an interferometer, detects the resulting ultrasonic displacement.

Particle size analysis is an essential analytical task in a large variety of processes of industrial and laboratorial relevance. Phase doppler anemometer (PDA) is one of well-established techniques allowing simultaneous measurement of velocity and size of particles, droplets, or bubbles in two-phase flows including spray atomization. The method is based upon the principle of light scattering interferometry. When a particle passes through the probe volume defined by the intersection of two laser beams, the phase of the light scattered by the particle carries information about the particle size,
