Need help determining what hardware to use

Solved!
Go to solution

       I will be conducting particle image velocimetry experiments on a rotating pump. A camera needs to take multiple pictures of the pump only when it is at a certain orientation. The pump will be rotating somewhere around 5000 RPM, and an encoder will transmit a pulse via TTL once every revolution. The camera/laser setup receives via TTL and can only operate at less than 15 Hz, so I need to build a setup that can receive this high frequency signal from the encoder, reduce it to the maximum frequency allowed by the camera, then output to trigger the camera. The system should be operated from a laptop computer.

 

       I know I'm a little foggy on the technical details, but I'm hoping someone can give me an idea of what hardware (chassis, modules, controller) I will need. Thanks for any help.

Hello JD_PUME,

 

Do you already have a camera in mind? Is the 15Hz limited by the laser?

 

If you dont have a specific camera in mind, I would suggest reading

Choosing the Right Camera Bus

http://zone.ni.com/devzone/cda/tut/p/id/5386

 

And typically, CameraLink cameras offer the best I/O synch.

 

You can use the link below to find out a list of cameras that we support

However, that would require you to have PCI/PCIe slot on your laptop. Other option would be to use our smart cameras such as 1722/1742 etc

 

Hope this helps.

Thank you for the help, Andy.

 

All I need the NI setup to do is receive a TTL signal at a high frequency, remove excess pulses to produce a lower frequency TTL signal, then output this signal through a coaxial cable. Apparently we have other hardware/software that takes care of the camera and laser from there. Also, laptop control is no longer necessary. I hope I'm getting closer to enough information.

Depending on how fast you wish to sample and how much resolution you would want, we have different family of cards that you can choose from.
