11.1. DBSD Calibration
11.1.1. First 7 Cells
Voltage calibration is a step that requires a setup with multiple tools and measurements. Below is the
suggested setup, which is also the one currently being used at LeddarTech. Note that the 300 mm distance
from the DBSD to the screen was selected so as to provide enough space in between each tile. A shorter or
longer distance can be selected.
