Chapter 5 TRIGGERING TYPES & CAPTURING METHODS 5.1 Triggering the LBA-PC The LBA-PC can support four basic types of triggering: • CW (or no trigger required), for lasers whose light output is continuous or pulsed at such a rate as to appear continuous to a camera (typically faster than 1000 Hz). • Trigger Out , for lasers that can be pulsed[...]

Since the perfect camera has not yet been found, we advise most LBA-PC users to operate pulsed lasers in Trigger Out mode whenever possible. Next best choice is the Video Trigger mode. These two modes will produce the most repeatable quantitative results. 5.1.2 Trigger Type CW The setup for CW timing is the least complex of the setups . Therefore, [...]

field rate of 60 Hz can cause a trigger pulse to ou tput at a 30 Hz rate. A non-interlaced camera running at a frame rate of 60 Hz can produce a trigger output pulse at a 60 Hz rate. 5.1.3.2 Trigger Delay The LBA-PC will produce trigger output pulses at the programmed frame Interval rate. With the Trigger Delay check box deselected, the trigger out[...]

5.1.3.7 CCD Frame and Interline Transfer Ca meras, Non-interlaced (Progressive scan) These camera types can produce 1x high-resolutio n images.

For example: If you are using an LBA-712PC frame grabber (a 12 bi t digitizer) you have the following possible Video Trigger Level choices: 256, 512, 1024, 2048. If you set the level to 512, the LBA will capture a laser beam pulse as soon as it detects a pixe l raw en[...]

Example: With the Capture Interval set to 10, and a 30 Hz frame rate camera, the capture rate will be 3 fps. 5.2.1.2 With Trigger Type set to Trigger Out The frame rate of the camera and the Trigger and Capture Intervals will combine to determine the capture rate. Example: With the Capture Interval set to 10, and the Trigger Interval set to 5, the [...]
