Laser Scanning for Eye Diseases
Laser Scanning for Eye Diseases Customer Case In scanning for non-ablative eye diseases, the customer has a requirement for high vertical resolution while remaining cost effective. By shooting a low-powered laser into the eye (low enough to not cause lasting damage), they are able to determine whether there are any problems in the eye cells. The laser does cause minute damage that is repaired by the antibodies of the eye. The requirement is to capture laser reflections and analyze them. The scan takes place over the entire eye and there are therefore multiple acquisitions. The main obstacle is that [...]

Why Demand for SiC Wafers is Soaring and Durable
Silicon carbide (SiC) wafers are in high demand, particularly in high-temperature applications. Silicon carbide (SiC), a semiconductor material made of both silicon and carbon, can withstand extreme temperatures of up to 2700°C. Often referred to as carborundum, SiC’s unique properties also make it a key material in non-electronic applications such as bulletproof vests, extrusion dies, sandpaper, and high-performance disc brakes. In the electronics industry, SiC wafers are crucial for devices operating under high temperatures, high voltages, or both. For example, they are used in electric vehicle (EV) power electronics, 5G communication systems, and LED technology, making SiC a material [...]
Echocardiography Experiment
Echocardiography Experiment Customer Case This customer is involved in an Echocardiography experiment. The customer already has an ultrasound imager with a built-in A/D converter which can output 12-bit image data which must be analyzed with the customer's proprietary algorithms on a PC platform. In order to accomplish this, it is required to bring 12-bit digital data at 35 MHz clock rate into a PC. This data is arriving in a burst mode with a repeat frequency of 12.8 KHz with 1000 samples arriving in 28 us followed by no data for the next 50 us. There are 512 such [...]
Wafer Stress Analysis Using the 300iSA
Wafer Stress Analysis Using MTI Instruments Proforma 300iSA Wafer processing involves several stages that can lead to mechanical changes in the wafer structure. These changes, or stresses, may result in deformities, making the wafer either unusable or only marginally usable. To evaluate these stresses and determine the wafer's quality, wafer stress measurement is essential. The Proforma 300iSA wafer characterization tool offers a powerful solution for wafer stress analysis. It allows for the analysis of a wafer both before and after processing. By comparing these two states, the Proforma 300iSA effectively evaluates the wafer's stress levels and mechanical alterations, providing [...]
Ultrasound Imaging
Ultrasound Imaging Customer Case This customer's application involves capturing ultrasound echoes from a medical imaging system, to be used in bedside monitors, defibrillators, intervascular ultrasound, ECG, etc. The live imaging rate is 30 frames per second (fps). Each image frame depicts a full 360-degree circular section. A frame is 240 echoes, so the pulse repeat frequency (PRF) is 7200 Hz, or one echo every 140 us. The customer anticipates signals at 50 MHz with a 50% bandwidth (the passband must extend to at least 75 MHz). The echo duration is 15 us; the signal size is roughly +/- 70 [...]
Ultrasonic Imaging
Ultrasonic Imaging Customer Case The customer is digitizing signals returned from an ultrasonic transducer used in the study of cardiac phenomena. At the moment, a 5 MHz transducer is being used, but the customer wants to upgrade to a 10 MHz transducer in the near future. This transducer will give him better spacial resolution. The customer needs one channel of very fast (100 MSPS), preferably 12-bit A/D conversion which is controlled by an external trigger signal. Bandwidth of the analog front-end of the A/D card or system must be very flat up to 15 or 20 MHz. The application [...]
Weathering the storm: Keys to resiliency in MRO
Weathering the storm: Keys to resiliency in MRO By Ken Ameika It’s no secret that COVID-19 has adversely affected the airline industry, and consequently the MRO and test cell markets. But the impacts are nuanced. Commercial aircraft utilization is way down; meanwhile, freight carrier business is expanding markedly. Operators are spending less; but they still have needs, which often require quick turnaround. It’s been hard for many. But there’s good news: COVID provided lessons that we can all use to make our businesses, or our careers, more resilient to the next major disruption. Diversify Your Business Commercial passenger traffic—or [...]
Ultrasound Tissue Imaging
Ultrasound Tissue Imaging Customer Case This customer is building a system to be used as a test station for examining human tissue for disease. Diseased organs differ from healthy organs in ways that can be measured via the echoes of ultrasound transmissions which are passed through the tissues. The customer's system will build a 3D image of the tissue under examination. In order to obtain a clear ultrasound image of the object being studied, the successive data captures have to be aligned to eliminate a distorted image. Jitter which would result from an asynchronous triggering is not acceptable. The [...]
Ultrasonic Medical Imaging System
Ultrasonic Medical Imaging System Customer Case A customer wants to construct an ultrasonic medical imaging system based on a transducer array. A central ultrasonic generation transducer generates a burst of ultrasonic energy which travels towards a tissue specimen. Echoes reflected off the tissue specimen are simultaneously detected by an array of 48 ultrasonic receiver transducers arranged in a dish-like pattern. The customer must simultaneously digitize all 48 signals and download them to PC RAM as quickly as possible. The customer requires 8 bit vertical resolution and would like to sample at 40 MS/s, but 20 MS/s would be acceptable. [...]

Ensuring the proper operation of your aircraft engine is essential to complying with manufacturers guidelines for the safety and longevity of the aircraft. Ensuring engines are not operating outside acceptible vibration limits and operating optimally isn't just smart, it is vital to your business. Excessive engine vibration can lead to cracked turbine, fan and compressor components potentially leading to catastrophic failure. The costs of catastrophic engine failure due to an unbalanced engine can measure in the millions of dollars. As airlines push to get more and more life out of their aging fleets, the need to properly maintain the [...]
