Abstract
The smartphones of today have come a long way from its first inception. Technologically they are highly advanced and can be put to various uses that could not be dreamt of, a decade back. There are instruments now out in the market which when combined with smartphones can become a powerful tool to conduct nondestructive evaluations. Yes, that’s right, NDE. These instruments can be applied to solve simple household issues. For example, detecting heat leaks using a detachable Infrared camera with the cellphone. In this presentation, results from android adaptable NDE devices and from standard NDE devices will be compared. The devices to be used are: • Eddy Smart - a transducer is attached to the phone that makes eddy current measurement on the specimen and stores data on the phone. • FLIR ONE Thermal Imaging - an Infrared camera that is attached to a smartphone through USB jack and relay The devices to be used are: • Eddy Smart - a transducer is attached to the phone that makes eddy current measurement on the specimen and stores data on the phone. • FLIR ONE Thermal Imaging - an Infrared camera that is attached to a smartphone through USB jack and relays heat images to the phone. • PCUS Pocket – This device is the size of a hard disk but makes accurate ultrasonic measurements at par with the standard devices, when connected to a laptop/PC. Test samples will be developed to quantify the performance of these low-cost systems. A comparison of the results from standard and smart, portable devices validate the performance of the new devices. It determines the areas where the technology needs to be further developed. Advantages and limitations of the android adaptable systems with respect to nondestructive testing will be discussed.
