[edit] Microscope Control Software

[edit] Hardware

At the MMVL a Linux software for controlling a Leica DM LAM microscope with a Basler A302fc IIDC/DCAM-compatible firewire camera has been developed.

[edit] Software

[edit] Features

The software uses OpenGL to display the camera image with a high framerate. The software already has the following capabilities:

• Move object table with mouse-dragging
• Camera-display with digital zoom (requires IIDC 1394-based firewire digital camera)
• Display and capture videos:
  • Colour images
  • Graylevel images
  • Edge images (thresholded Sobel)
• Capture focus stacks

[edit] Implementation

The implementation took maybe 15 days. Before being able to develop the application itself, the Mimas-library had to be enhanced with firewire digital camera input, the existing libserial-library had to be enhanced with timing functionality and the required part of the serial communication with the Leica DM LAM microscope had to be implemented under Linux.

[edit] Download

• You need to have Qt3 and libdc1394 on your computer.
• You need to install libserial-0.4.1.tar.gz (195 kByte).
• You also need Mimas-1.4 (12.2 MByte).
• Finally you need to install leica.tar.gz (32 kByte).
