Paper Abstract

This paper describes a multiplex image coding system designed to be associated with a non-imaging spectrometer (Si(Li) or thermal spectrometer). The resulting instrument, an imaging spectrometer, could be used as a focal instrument for an astronomical grazing incidence telescope. The coding system consists in a movable mask with pseudo randomly distributed holes, located in the telescope focal plane. The pixel size lies in the range 100-200 microns. The close association of the coder with a Si(Li) spectrometer or with an X-ray bolometer gives an imaging spectrometer combining the good efficiency ( >50% between 0.1 and 10 keV) and energy resolution ( ΔE~100 eV for Si(Li),~ 10 eV (expected) for a bolometer) of these energy dispersive devices, with the spatial resolution of the mask.
