Laue experiment · Instrument control
A desktop interface for positioning a crystal, finding its centre of rotation and recording Laue diffraction images.
Robot motion, live camera views and acquisition controls come together in one workspace.
The operator starts the application, selects Grab Gonio and then Move to Camera. The interface and robot view show the sample moving into position for camera-guided alignment.
The experiment workflow
These recordings are sped up 3×; instrument motion is not shown in real time. Pause or expand a clip to inspect the controls.
Translate the Meca500 arm or rotate about a defined centre of rotation. Switch between fixed laboratory axes and the changing axes of the goniometer convention.
The coordinate convention stays explicit while the sample orientation changes.
Use the two live IC-camera views to mark the sample position and set its centre of rotation. The same workflow then moves the sample to the X-ray alignment position.
Camera feedback connects the physical sample to the robot's positioning reference.
Set the exposure, capture a Laue image and save it through the PS-camera module. The diffraction view sits alongside the positioning controls.
Keep acquisition and sample positioning in the same experiment workspace.
My contribution · Integration & coordinate handling
I integrated robot control, camera monitoring and Laue image acquisition into a single interface, and connected robot motion to the goniometer conventions used in the experiment.
