System Architecture
- One "Master Channel"
- One or more "Slave Channels"
- 1 Basler Sprint bilinear color line-scan camera
- 1 Strobed illumination device
- 1 Camera, Illumination and Acquisition controller (CIAC).
The Master channel includes:
- 1 Camera Trigger Source circuit that generates the SyncBus:Camera Trigger signal.
- 1 Acquisition Enable source circuit that generates the SyncBus:Acquisition Enable signal.
The SyncBus distributes the two signals to the Camera, Illumination and Acquisition Controller of all participating channels.
The leading edge of the SyncBus:Camera Trigger signal triggers simultaneously all camera and illumination controllers. Each controller sends an Exsync pulse (MultiCam reset signal) having a specified width to the camera. It generates also a strobe pulse once every two Exsync.
The leading edge of the SyncBus:Acquisition Enable signal initiates the image data capture on all channels. The image data capture effectively begins on the next occurrence of a line A ensuring that the image data capture begins always on a boundary of the 2x2 Bayer CFA pattern.
The falling edge of the SyncBus:Acquisition Enable signal terminates the image data capture on all channels. The image data capture effectively terminates after the next occurrence of a line B ensuring that the image data capture terminates always on a boundary of the 2x2 Bayer CFA pattern.
