Using multiple Matrox Altiz units
In our example, we connected AUX_OUT4 of ALTIZ 1 to AUX_IN0 of ALTIZ 2 and 3. Other input and
output pins can be used, as long as they are free.
In the case of an overlap between the FoVs, the exposure window of two adjacent AltiZ units must be
offset to avoid artifacts introduced by the neighboring laser. Line acquisitions on ALTIZ 1 and ALTIZ 3 are
triggered simultaneously, and then ALTIZ 2 is triggered when the exposure of both ALTIZ 1 and ALTIZ 3
turns OFF.
The ON to OFF response time is 35µs and the OFF to ON response time is 55µs, as outlined
in the Electrical Specifications section of Appendix B in the Installation and Technical Reference manual.
This results in a duration limit for the exposure time:
100µ�� < ���������������� �������� <
With more than two AltiZ units, a programmable delay of min 20µs (T
between the end of exposure on AltiZ 1 and the exposure start of AltiZ 2.
