Displays received waveform as it is. The conditions of concrete directly
underneath the Handy Search are displayed as reflected waveform in real
time.
Displays the vertical cross section of a scan point by gradating the
reflected waveform shown in A mode according to reflection intensity and
continuously displaying it.
Displays both B-mode and A-mode images at the same time.
Image processing that uses internal fixed surface wave data to
automatically remove the wave reflected from the surface of the concrete
during scanning and only shows the reflected wave from rebar etc.
Image processing used in the case that the effect of the reflected waves
from the surface of the concrete can not be fully removed using the
internal fixed surface wave data of the real time auto surface wave
processing. Thus, reflected waves in the form of stripes remain in the
scanning results.
Image processing where an arbitrary line is designated while scanning.
The data of the designated line is subtracted from the scanning results
data, and the reflected wave from the concrete surface is automatically
removed. Thus, only the reflected waves from rebar etc. are shown.
Image processing where an arbitrary line is designated from scanning
results. The surface portion of the data from the designated line is
subtracted from the scanning results data, and the reflected wave from
the concrete surface is automatically removed. Thus, only the reflected
waves from rebar etc. are shown.
Image processing that shows only the waveform of the first peak on the
+side of the scanning results.
This enables removal of multiple reflected signals and only displays the
upper rebar.
Image processing that uses internal fixed surface wave data to remove
the wave reflected from the surface of the concrete and only shows the
reflected wave from rebar etc.
Image processing where an arbitrary line from the scanning results is
designated and the designated line is subtracted from the scanning
results data. Stripe reflected waves throughout the entire depth, such as
reflected waves from the concrete surface and reflected waves from the
rear surface etc., are removed and only the reflected waves from rebar
etc. are shown.
This processing restores the image processing result to the original state
and displays unprocessed raw data.
Method that performs scanning in accordance with Handy Search's
traveling distance, using the distance detector mounted on the wheels of
the Handy Search.
Method that performs B-mode scanning at preset time intervals,
regardless of movement of the Handy Search.
Object-specific coefficient. The radio wave propagation rate changes with
the value of the relative permittivity. Therefore, the wave propagation
velocity and scanning depth change change based on the relative
permittivity of the concrete. Calculation error of scanning depth can be
reduced by setting a depth calibration value.
