Fast UV slitless spectrometer for meteor research

摘要

Abstract: We have designed a wide-field, objective grating spectrograph based on a Schmidt optical system, similar to one flown in sounding rocket investigations by the Naval Research Laboratory. The instrument covers a field of view 10 degrees in diameter, has a spectral range of 130 - 300 nanometers, and utilizes a solar blind image intensifier tube coupled to a CCD array camera. The instrument could be flown as a Shuttle Hitchhiker payload, in a Spartan mission, or (eventually) as a Space Station attached payload. Another possible application of the instrument would be to observe any UV emission from lightning `sprites', which would be prominent if these extend to high enough altitudes to be above a significant portion of the ozone layer.!21
