LightCommander Subwindow / Subregion to get >5000Hz frame rates possible?

Jeffrey Lee88107

Hi,

I would like to use my Lightcommander to display a sequence of binary patterns at 100kHz frame rate. The time resolution that is displayed and detected is set by number of images in the sequence as well the frame rate. For example, if I wanted to display a rotating object doing one revolution @ 1Hz with 1us time resolution, I'd need 10^6 images in the sequence and to display them at 1MHz frame rate. This cannot be done with the standard LightCommander Control Software which has a limited staticimage storage of ~1000 binary images (1024x768) and max frame rate of 5kHz. Would it be possible to work with smaller resolution (100x100 for example) to increase the number of storaged static images? Also, with these smaller images, can I get the frame rates up to 100kHz by subregioning/subwindowing and/or binning? I'd very much appreciate any advice or links to resources. Thanks

    Hi Jeffrey,

    Welcome to DLP & MEMS forum.

    LightCommander(TM) at present supports only refreshing of entire DMD and the load time of the DMD is 200uSec this leads to a binary frames refresh rate of 1/200 = 5000Hz.

    Partial loading and refreshing of the DMD is not supported in the system at present. However we will note this for future enhancements.

    Regards,

    Thank you, Sanjeev, for the quick response. I was hoping there was some command to "STOP" after just a portion of the DMD was updated and move on to the next static image in sequence. I'd definitely recommend this feature for future releases and perhaps even the "bin" would be great.
