Research possibilities:

It is a fully automated system with full control of the microscope setup, the operating parameters of lasers and stepless confocal aperture. Its key features include the ability to register up to 6 independent channels and their overlap, MULTITRACKING option that allows registration-free phenomenon of cross-talk with overlapping issues, ease of use thanks to the muli- excitation function REUSE software and recording of fast processes.

Scanning Acoustic Microscopy SAM

The acoustic microscope works in the pulse reflection method. The most important component in the scanning acoustic microscopy is a high frequency piezoelectric sound transducer. This object transmits and receives sound pulses of high penetration rate. It is a sapphire cylinder with a ZnO film (1). A transducer generates a ultrasound pulse (piezoceramic layer converts electromagnetic vibrations into sound wave) which propagates along the delay rod. The transducer is immersed within a coupling medium (water). The immersion system cavity is therefore the acoustic spherical lens. A lens focuses beam within the sample. The acoustic objective receives the sound reflections from the sample. The information follows to the return to transducer. There transforms them into electromagnetic pulses detected by an oscilloscope and on the monitor display them as a pixel. The acoustic objective scans the sample line by line. Figure 3 shows a scheme of an acoustic microscope system.

 Figure 3. Scheme of the Scanning Acoustic Microscope

The result of the SAM is determined by aperture and acoustic wavelength, which is depends on the material but this microscope can detected damage to a minimum size of 0,3 µm. Depending on the critical defect size and defect depth the working frequency and transducer design have to be chosen. The important information is that the SAM works in real time mode. The scanning acoustic microscope is equipped with a 4 heads (15MHz, 75MHz, 110MHz, 180MHz).
The Scanning Acoustic Microscope works on several modes (Figure 4). A 2D scan gives information about x-y plane and 3D scan image provides information about x-y plane and the time of flight the acoustic beam. The most popular are scan A, scan B, scan C and scan X. Scan A mode is used to characterize a single point of interest in a specimen. The B-scan mode generates a top-down or X-Z axis image. The C-scan is a compilation of A-scan but not in one point but along X-Y axis, they a display of the image of reflected echoes at the focused plane of sample. Scan X is used to view image at a depth of the sample.

Having described the principles of the scanning acoustic microscope is now presented same results. The scanning acoustic microscopy is being used to analyse: bonded and soldered structures, castings, interface and semiconductor components, material stress and crack propagation, interface evaluations of thin coatings, biological, geological and ceramics structures, detection of delaminations in packages, 3-dimensional imaging of welding, determining volume defects .
One of the applications of the scanning acoustic microscopy was in the study of bio-ceramics mater. In Figure 5 is presented an acoustic image of hydroxyapatite sintered at various temperatures. This material is characterized by inhomogeneous and different pores sizes.

The SAM is a good techniques to detect small defects in the surface and under the surface. Using this technique it is possible to find cracks smaller than 1 µm. Surface near cracks, delaminations, void or inclusions due to their different elastic properties from the surrounding materials. In figure 6 is presented an acoustic identification of the defects within the massive forging ingot. The SAM identification of defects at difference depth from the surface. In the figure 6 are visible defects (holes), contains a carbon stalagmite (yellow arrow indicates the carbide localized inside the void) and some porosity. In figure 7 is presented a deeper layer in this material (forging ingot).
