3D Data Type output format description

XZ (CalibratedAC)
This output format takes into account that the resolution varies in the X and Z directions. So, any
raw value in X and in Z is "compensated" for this variation; this process is done automatically in
the sensor, which outputs "calibrated" data. The calibrated data must be multiplied by a scaling
factor to obtain the real-world Z value in the specified measurement unit. Each profile therefore
consists of X and Z values.
•
Output is 32 bits, consisting of calibrated X data (16-bit) and calibrated Z data (16-bit).
There are about 2K 32-bit output data words indexed by the 2K X-axis points.

The calibrated Z data (16-bit) must be multiplied by the Z scale factor to obtain the real-
world Z value in the specified measurement unit.
•
The calibrated X data (16-bit) must be multiplied by the X scale factor to obtain the real-
world X value in the specified measurement unit.
•
Z-Expert graphs the Z output data in the selected measurement unit at each X point;
floating the mouse over the profile will show the calculated real-world X measurement
relative to the left edge of the measurement area.

Calibrated Profile Depth
XZRW (CalibratedACRW)
Each profile consists of calibrated X and Z data (as in the XZ format), reflectance R, and
multipurpose W (typically peak width) values, in a 64-bit data format.
•
Output is 64 bits, consisting of calibrated X data, calibrated Z data, reflectance, and W
(multipurpose) data.
