3.1.1 Linear Scan

a) Definition

Linear scan, also called electronic scan or E scan, is a scanning method with a fixed number of

elements scanning along the probe arrangement direction in the same focus rule until the whole

probe scanning is finished.

That is to add a select window with a fixed size on the phased-array probe, and the elements in

that window are T/R elements. When transmitting/receiving of elements in the window is finished,

shift the window at a fixed interval to select the T/R elements for the next transmission/ reception

without changing the focus rule, and it works in the same way till the whole probe selection is

completed, which is similar to manual straight-line scanning with a conventional probe. The

scanning principle is shown in Fig. 3-1, and the image display as in Fig. 3-2.

Fig. 3-1 Linear Scan Diagram

(Every three elements in one group, and scan at an interval of one element)

Chapter 4Phased-array Image Measurement

The phased-array image measurement of this system includes: gate measurement and cursor

measurement. The gate measurement is to measure wave and depth, and the cursor

measurement is to measure horizontal position.

4.1 Measuring Zero

The measuring zero of phased-array image is a reference point of coordinate zero on the image,

which enables the user to measure the relative position of flaws on the image. Therefore the

position of the measuring zero can be determined by the user. For easy description, the measuring

zero is defined as: the interface between the probe (wedge) and the work piece in depth direction,

or certain position of the probe (wedge) in horizontal direction. The horizontal zero recommended

for different probes (wedges) is not the same. See the detailed description below.

a) The vertical and horizontal zero of 0-degree phased-array probe (wedge) is as shown in

Fig. 4-1.

5.2.3 Delay Calibrati on

Delay calibration consists of probe delay and wedge delay. Generally, there are two methods:

sound path calibration and depth calibration, which can be found in Fig. 5-31, Fig. 5-32 and Fig.

5-33. Sound path calibration and depth calibration method 1 are usually used to calibrate angle

phased-array probe, and depth calibration method 2 is mostly used to calibrate 0-degree

phased-array probe.
