Optical fibres

Several studies concerning optical fibres were performed. These include:

• The reduction of the focal degradation in the optical fibres caused by mechanical pressure.
• Interferometrics techniques with optical fibres to applied in astronomy
• Micro-polishing to optical fibres with diamond solution
• Development of the proceeding to measure by optical techniques the precision of the holes in a micro hole metallic array.
• Development of the technique to measure the point spread function from optical lenses.

Developent of scientific software

Eucalyptus and SIFUS:

In collaboration with researchers of the IAG/UPS and the UFSC the reduction software for the Eucalyptus and SIFUS 2D spectrographs is developped. I tis intended to provide the means for doing quick look at the telescope and the data reduction software to reduce the data during the observations or in the next day. The only step that is specific to SOAR-IFU reduction is the extraction of the fiber spectra from the initial CCD image. It is expected that everything else could be done using standard packages such as IRAF. As for looking at the final 3D data, there are also existing packages that can do this. We intend to develop a task similar to 'ldisplay' in the 'gmisc' package as a quick look tool. The status of the software and more details can be found at http://bela.lna.br/~bruno/Ifu/ifusoar.html (B.V. Castilho)

MIRA:

The software system MIRA for general data reductions in astronomy was enlarged and perfected. (A. Bruch)

Optical fibres:

A special software to obtain the curves of the focal degradation of optical fibres was developped. (A.C. de Oliveira)
