In order to record the data corresponding to the CHRocodile C unit, the Ethernet port or the
RS422/RS232 communication port must be connected to the computer.
It is now possible to perform an area scan:
- In order to scan the target, one can move the optical probe or the target inside optical axis
perpendicular plan. Thus, a 2 axis translation system is required. The altitude or thickness
data is recorded during the scan. In order to synchronized the data acquisition with the moving
session, one need to connect the trigger in/out to the translation system. The command TRG,
enables an exact alignment of the sensors sampling intervals with the movement of a
scanning axis.
- However, if scan velocity is not constant, the pitch between each recorded point is not
constant and the global topography will be distorted. To overcome this image deformation it is
important to assign precisely each measured points and axis positions. To do so, one need to
connect the incremental encoder-input. The CHRocodile C can manage with 2-axis Encoders
using the analogue converter box accessory.
