5.8 Image Stabilizer
Used to reduce flicker on the real-time B-scan image.
The image displayed on the screen is a combination of the latest real-time image data
combined with a percentage of the previous image data.
The percentage is determined by the slider.
Slider set to 1 = no stabilization – Image presentation is immediate, but it flickers.
Slider set to 8 = maximum stabilization – Image takes longer to build up, but there is
no flicker.
5.9 Advanced Settings – Half Cycle
This setting can help to distinguish near-surface objects that are close to each other.
In transmission, the transducers are driven by a high-voltage square wave.
Switching on the Half Cycle button uses a half pulse with a single polarity. As a result, the
generated ultrasonic pulse has also a shorter duration, which improves the resolution along
the depth (z) axis. The drawback is a shorter amount of transmitted energy, so the signal-to-
incoherent noise ratio is lower.
