Paper Abstract

We describe a novel technique which enables us to conduct two-dimensional imaging spectroscopy using a one-dimensional imaging spectrometer. A typical imaging spectrometer obtains a series of one-dimensional monochromatic images containing the entire field of view, but the spatial information in the dispersion direction is lost. By rotating the instrument (hence rotating the field of view) we compile a series of time dependent profiles. We use a numerical tomographic reconstruction method to recover the second spatial dimension and thereby obtain two-dimensional monochromatic images of the field of view. This technique is more sensitive and hence collects a full two-dimensional image more quickly than a conventional push-broom scan. We present the results of numerical simulations and discuss the prospects of this method for magnetospheric imaging applications.
