| contents | Integral Field Spectroscopy for panoramic telescopes Jeremy Allington-Smith Física, Astronomía y Matemáticas INSTRUMENTATION: SPECTROGRAPHS TECHNIQUES: SPECTROSCOPIC The basic principles of integral field spectroscopy are reviewed using a figure of merit, the specific informationdensity, as an objective means of comparison. This shows that the best method in theory is image slicing,especially as implemented in the Advanced Image Slicer design used in the Integral Field Unit of the GeminiNear-Infrared Spectrograph. However, an alternative, a hybrid of lenslet array and slicer techniques, may offera better compromise between theoretical performance and practicality for panoramic spectroscopic surveysrequiring millions of spatial elements such as the San Pedro Mártir twin telescope project. Conceptual designsof this type already exist, including one aimed at the IMACS spectrograph on Magellan 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102804 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.28 |
