DOLPHITECH MATRIX TRANSDUCERS VS PHASED ARRAY
Phased array transducers contain a number of individual transducers that can be pulsed individually to steer and
Dolphitech Matrix transducers have transducer elements placed in a 2-dimensional array. Since the transducer directly covers the area of inspection, no encoder system is needed to calculate the position of each element. Reducing risk of positional errors due to faults or imprecision in the encoder system.focus the sound beam in a specific direction. Linear arrays are typically used in combination with an encoder system matching the signal with positional information to build a 2-dimensional image. Price will increase with the added number of elements and element gets smaller in size.
Substantial improvements in resolution are to be expected from a Dolphicam Ultrasound camera system compared to an Olympus MX phased array system.
MORE DATA THAN WE CAN USE
The TRM has 128 horizontal and 128 vertical transducer electrodes. This makes a transducer element where one horizontal line crosses a vertical line. I total 16.384 transducer elements send and receive sound to create the data with a frame rate from 10 to 100 frames per second.
In short, our scans deliver more data than we can use for now. For you, this means that the product you buy today only will get better tomorrow.
ULTRASOUND THAT LOOKS AND SOUNDS BETTER
Spend less time calibrating and more time fixing. Turn on the device and start scanning (1 min from start to ready to scan).
Large amounts of Data is being processed to a user-friendly dashboard. The «Traffic lights» pallet or real-time dataset streaming visualizes the scan in a way that impresses experts, and lets non-experts understand what they see.
SMALL, FLEXIBLE, AND EASY ACCESS
The TRM is made small and ergonomic, it fits nicely in your hand. Its size and weight makes it easy to hold, and access places that are really difficult to scan.
GET THE BIGGER PICTURE WITH STITCHING
Depending on your needs for accuracy and speed, we can offer different ways for scanning large areas and combining into one image. Dolphicam comes with multiple different stitching solutions, from manual grid tool to fully automated systems.

The dolphicam2 can be used on material up to 60mm however this is dictated by the ability of the material to transmit ultrasound. The target material’s physical and chemical properties, as well as the ultrasonic frequency chosen, will all influence the dolphicam2’s penetration depth and its corresponding maximum inspection thickness.
We have achieved sub-millimetre detection in a range of materials. The material thickness and the ultrasonic frequency chosen will influence this resolution. The short wavelengths generated by higher frequencies provide superior resolution. This is how bats can use ultrasound to echolocate and catch insects, whereas we can’t do the same with our lower pitch voices!
Yes, this can be achieved in two different ways. If individual voids are large enough, such as for needle voids, they can be resolved and measured directly using our geometrical measurement tools. In cases where micro pores may be too small to resolve explicitly, they can be detected via a reduction in the back wall signal amplitude. This effect can be quantified over a given area using our statistical measurement tools.
The dolphicam2 software offers a range of different display configurations, providing various combinations of A- B- and C-scans, as well as our 3D visualisation window. These layouts have been tailored to best suit the data being generated. Users can also manipulate the certain displays such as the gates, color palettes and measurement tools on the screen.
The dolphicam2 transducer module (TRM) works using a crossing electrode principle. Across the face of the transducer, 128 transmitter electrodes cross with 128 receiver electrodes. Between the two electrode layers, a piezoelectric material is placed which converts electrical energy to mechanical (sound) energy. To collect a pulse-echo-signal from a transducer element, a 70V pulse is excited on the transmitting electrode creating an ultrasonic pulse along the entire electrode. The ultrasonic pulse goes into the material and the reflected signal is sampled on one receiver electrode. In other words, each crossing point between the electrodes becomes an ultrasonic element, providing an aperture of 16,384 (128x128) elements.
At the moment we do not, they are all 40mm x 40mm. However, we take full advantage of the 128×128 matrix array in our current range of probes to provide a superior level of detail in real-time and in three dimensions.
We have a range of options available for larger area C-scan mapping. These include manual stitching, our GridTool and RapidMapper accessories, and using one- or two-axis encoders.
The dolphicam2 Blackbox and TRM are IP66 rated, which means they can withstand powerful dust and water jets, however should not be fully submerged underwater. It’s safe to immerse the front face of the TRM in few millimetres of water for a water-coupled inspection.
We offer curved delay lines that are matched to fit pipe outer diameters down to 50mm (2”). For more information, please visit https://www.dolphitech.com/products
The dolphicam2 platform provides straight beam inspection with unparalleled resolution.
The dolphicam2 can be used for to inspect a wide range of glass and carbon fibre reinforced composites as used in automotive, aerospace, defence, and energy markets. It can be also used to inspect metals in these sectors, as well as for adhesive bonding of similar and dissimilar materials. Finally, plastics, multi materials and some ceramics can also be inspected. View our capability studies here.
The TRMs are highly ergonomic and easy to manipulate. With our softer delay line Aqualene and Aqualink models, this can conform to some curvatures. For fixed curvatures such as pipes, we offer a range of curved pipe shoes which match the outer diameter of the pipe
Interchangeable delay lines are available on some TRM models.
