OPTRONIS Cyclone

High-speed CoaXPress cameras (Cyclone-25-150-M, -1HS-3500-M, -2-2000-M) with a Euresys or BitFlow frame grabber.

Models
Cyclone-25-150-M, Cyclone-1HS-3500-M, Cyclone-2-2000-M
Connection
CoaXPress (PCIe frame grabber)
Driver software
Euresys eGrabber or BitFlow SDK
In PIVlab select
PIVlab LD-PS + OPTRONIS Cyclone

Supported models: Cyclone-25-150-M, Cyclone-1HS-3500-M and Cyclone-2-2000-M. PIVlab detects the model automatically and records 8-bit images.

1. Install the software

Standalone app

BitFlow frame grabber

  1. Install the BitFlow CoaXPress frame grabber in a free PCIe 3.0 (Gen 3) x8 slot of the computer.
  2. Install the BitFlow SDK.
  3. Install the BitFlow MATLAB IMAQ adaptor.

Euresys frame grabber

  1. Install the Euresys Coaxlink Quad CXP-12 frame grabber in a free PCIe 3.0 (Gen 3) x8 slot of the computer.
  2. Install eGrabber for Coaxlink from the Euresys download area (at the time of writing: egrabber-win10-x86_64-24.04.0.2.exe).

MATLAB toolbox

BitFlow frame grabber

  1. Make sure the Image Acquisition Toolbox is installed. Many university MATLAB licences include it.
  2. Install the BitFlow CoaXPress frame grabber in a free PCIe 3.0 (Gen 3) x8 slot of the computer.
  3. Install the BitFlow SDK.
  4. Install the BitFlow MATLAB IMAQ adaptor.
  5. Install the Image Acquisition Toolbox Support Package for GenICam Interface.

Euresys frame grabber

  1. Make sure the Image Acquisition Toolbox is installed. Many university MATLAB licences include it.
  2. Install the Euresys Coaxlink Quad CXP-12 frame grabber in a free PCIe 3.0 (Gen 3) x8 slot of the computer.
  3. Install eGrabber for Coaxlink from the Euresys download area (at the time of writing: egrabber-win10-x86_64-24.04.0.2.exe).
  4. Install the Image Acquisition Toolbox Support Package for GenICam Interface.

2. Connect the camera

  1. Connect the camera to the frame grabber with the four coaxial cables, in this order: 1-A, 2-B, 3-C, 4-D.
  2. Connect the trigger cable from the camera’s Aux port (Sync in) to the synchronizer or laser.
  3. Power the camera with the supplied power supply (or directly via CoaXPress).
  4. Check the back of the camera: all four lights are solid green when the connection is ready.

Set the camera to external triggering (Euresys only)

With a Euresys frame grabber, the camera has to be set to external triggering once, in eGrabber Studio. The setting is stored in the camera. Cameras bought from OPTOLUTION are already set up, so you can skip this step.

  1. Open eGrabber Studio and make the settings shown in these screenshots:

    eGrabber Studio, step 1

    eGrabber Studio, step 2

    eGrabber Studio, step 3

    eGrabber Studio, step 4

    eGrabber Studio, step 5

  2. Power cycle the camera and click the refresh button:

    eGrabber Studio, refresh after power cycle

  3. Check that the changed settings are still there after the power cycle.

3. Start capturing

  1. Start PIVlab and open the image acquisition panel.
  2. Select the configuration PIVlab LD-PS + OPTRONIS Cyclone. The camera model is detected automatically.
  3. Connect to the synchronizer / laser in PIVlab and start your PIV recordings.

How many images fit into RAM

High-speed recordings go into the computer’s RAM first, so that no frame is lost, and are saved to disk afterwards. Approximate number of double images with a Cyclone-2-2000-M (8 bit):

RAM Double images
16 GB 1300
32 GB 3400
64 GB 7500

PIVlab shows the maximum for your computer: if you ask for more images, the field turns orange and PIVlab warns you before recording. A fast, large SSD makes saving the recording quicker.
