GENERATING THE BD SIGNAL
The BD signal is used to enable synchronization in main scanning direction, and it is generated
by the BD PCB based on the laser beam reflected by the BD mirror found in the optical path.
The BD signal is used to send video signals from the image processor PCB to the laser
controller PCB. The laser controller PCB is designed to correct video signals, and the laser driver
PCB is used to send out video signals as laser intensity control signals in sequence.
