Machine Vision Strobe Controller Synchronization Guide
Strobe synchronization freezes motion only when trigger timing, exposure window, light pulse width, controller current, and thermal duty cycle are aligned. Treat the controller, camera, light, and line speed as one timing system.
Timing inputs
- Camera exposure time
- Trigger source and latency
- Light pulse width
- Line speed or part speed
- Required brightness at working distance
Controller checks
- Peak current rating
- Duty cycle limits
- Channel count
- Trigger polarity and delay
- Cable and connector current capacity
Failure modes
- Pulse outside exposure window
- Overdrive overheats LEDs
- Brightness changes with duty cycle
- Motion blur remains because exposure is still too long
