| Abstract: |
A fiber optic array, called DensePak, is used to obtain spectra over a two-dimensional spatial area. Such a device is useful for observations of QSO's, galaxy rotation curves, interacting galaxies, nova shells, planetary nebulae, H II regions, planetary atmospheres, and comets. A brief description of the image reconstruction technique is given. Following monochromatic image reconstruction, the images are stacked to form a data cube with two dimensions corresponding to the spatial dimensions on the sky, and the third dimension corresponding to the velocity along the line of sight. A comparison of a reconstructed DensePak image is made with a resampled direct CCD image. Discussion is also given regarding a SuperDensePak which would provide 1 arc-second sampling over a larger field of view than the present DensePak provides. |
