| Popis: |
The ESRF has released the first version of a low-cost image acquisition and processing system based on a industrial VME board and commercial CCD TV cameras. The images from standard CCIR (625 lines) or EIA (525 lines) inputs are digitised with 8-bit dynamic range and stored in a general purpose frame buffer to be processed by the embedded firmware. They can also be transferred to a UNIX workstation through the network for display in a X11 window, or stored in a file for off-line processing with image analysis packages like KHOROS, IDL, etc. The front-end VME acquisition system can be controlled with a Graphic Users' Interface (GUI) based on X11/Motif running under UNIX. The first release of the system is in operation and allows one to observe and analyse beam spots around the accelerators. The system has been extended to make it possible to position a mu sample (less than 10 μm 2 ) not visible to the naked eye. This system is a general purpose image acquisition system which may have wider applications. |
