A Remote Tone Burst Pulser Design for Automated Ultrasonic Scanning Systems

In this work,a programmable remote ultrasonic tone burst pulsercircuit design and implementation for Automated Water Squirting Ultrasonic Scanning Systems (AWSUSS) arepresented. This pulser can be configuredby a PC over RS422 communication interfacethusparameters such as pulse frequency, pulse repetition frequency (PRF), number of pulses in a burst,and pulse type (Positive/Negative Squared Waveor Bipolar) are set by user. High-voltage tone burst pulser can be adjusted between ±150V in 300V range. Hardware designof the pulser was made by usingaMicrosemi DRF1400 Class D half...

A physical layer implementation on reconfigurable underwater acoustic modem

Underwater acoustic (UWA) multi-user network algorithms can only be fully tested through experimental studies where communication signals are transmitted through a real underwater channel. Reconfigurable UWA modem provides a flexible environment for the testing of different communication algorithms including networking protocols. In this paper we present design, implementation, and testing of a physical layer algorithm on reconfigurable acoustic modem. This physical layer is very flexible; therefore it can easily be modified in order to be employed for the testing of...

Smartphone controlled ultrasonic nondestructive testing system design

The aim of this work is to design an ultrasonic non-destructive testing (NDT) system that utilizes the advanced features of smartphones and tablets. These superior features of smart devices can be listed as wide and sensitive touch screen, mobile internet connection, satisfactory CPU performance, application development environment and more. Integrating these features into a conventional NDT system increases the capabilities of the system while decreasing hardware costs. Therefore, an ultrasonic development card was designed in order to obtain these advantages....

Custom Design Fruit Quality Evaluation System with Non-Destructive Testing (NDT) Techniques

Quality evaluation of agricultural products is most commonly conducted using destructive methods. Ripeness and maturity of fruits are determined by measuring internal and external characteristic of fruits. Destructive method enables to measure texture, color, sugar content etc. Destructive methods increase success rate of quality determination of fruits, however, it practically has many concerns about effectiveness, reliability and cost. Therefore, it is necessary to develop fast, portable and cost-effective techniques without harming fruits to meet demand of consumer for fresh and...
