Disable laser via API

Follow
Adam

Hi,

I'd like to understand how to disable the laser on the L515 via my code, to avoid having a complex external trigger system. My use case is fairly slow (not real time).

I have read through this article https://dev.intelrealsense.com/docs/lidar-camera-l515-multi-camera-setup and would like to avoid the complexity of that setup for my use case if possible.

If it is not currently possible, is it something that you might support in the future?

Thanks in advance.

    Hello Adam,

    It is possible to turn off the laser completely by setting the option RS2_OPTION_LASER_POWER to 0. Refer to this list of options for RealSense cameras. The L515 does not support all options but you can see the supported options in RealSense Viewer.

    rs2::pipeline pipe; 
rs2::pipeline_profile selection = pipe.start();
rs2::device selected_device = selection.get_device();
auto depth_sensor = selected_device.first<rs2::depth_sensor>();

if (depth_sensor.supports(RS2_OPTION_LASER_POWER))
{
    // Query min and max values:
    auto range = depth_sensor.get_option_range(RS2_OPTION_LASER_POWER);
    depth_sensor.set_option(RS2_OPTION_LASER_POWER, range.max); // Set max power
    depth_sensor.set_option(RS2_OPTION_LASER_POWER, 0.f); // Disable laser
}

    Sincerely,
    Jesus G.
