19 July 2010Achieving reusability in KMOS instrument software
through design patterns
KMOS is a near-infrared multi-object spectrometer, which is currently being built by a British-German consortium
for the ESO VLT. As for any other VLT instrument, the KMOS instrument software is based on the
application framework given by the VLT Common Software, but faces particular design challenges in addition.
As separate parts of the software require a similar functionality with respect to mechanical and optical permissibility
checks, user interface, and configuration control, a number of tasks have to be implemented twice and
slightly differently. It turns out that most of these issues can be tackled successfully by means of well-known
object-oriented design patterns, providing for reusability and improving the overall software design. We present
a set of sample problems along with their particular pattern solution.
