Using LCr 4500 EVM as Active Illumination for Imaging

I am thinking about using LCr 4500 EVM as active illumination for imaging. At this point, only thing I want LCr 4500 to do is lighting my target with a sequence of specified colors. And imaging will be done with a high-speed camera with external trigger. 

Now my questions are:

1. Is this possible with LCR 4500? I thought about simply using video mode with pre-defined images but I realized video mode is displaying images with 60Hz. This might cause flickering problem with the high-speed camera. And then I am not sure structured light mode has color option in GUI application.

2. If this is possible, how can I do it with GUI or programmatically (preferred method)?

3. Is there any recommended procedure for color calibration with LCr 4500?

    #1. We recommend using the Pattern Sequence mode. Also recommend triggering your camera with trigger o/p for EVM, this is the best approach for synchronizing the two and camera is able to capture precisely.

     #2. Yes, please refer to the EVM user's guide and step through the Pattern Sequence Mode operation. Also we release the GUI source code, from which you can control programmatically. One of the user of the forum posted git repo here you can leverage the same https://github.com/jaybo/LightCrafter4500 

    #3. Please explain what do you mean by color calibration, also the provide details about what you intend to do (aslo calibration procedure steps)

    Sanjeev,

    Thanks for your prompt response and valuable information.

    As you recommended, I tried the device and GUI software, and looked into source code of the GUI.. In the end, I could find how I can achieve my goal. Thanks again for your help.
