LISA - A limb imaging spectrograph for airglow
Abstract
Limb imaging spectrographs for airglow scheduled to be launched on a sounding rocket with the objective of studying the chemistry of the lower nighttime thermosphere are discussed. The optical, mechanical, and detector designs are considered as well as the theoretical specifications for a prototype imager (255-328 nm). The basic design drivers for the LISA imagers are the spatial distributions of the airglow emissions, the nature of the spectra, the location of the imagers relative to those emissions during flight of the rocket, and the necessity to make the instruments light and compact. The optical design drivers are high resolution and as high a throughput as possible consistent with a compact package. It is pointed out that the LISA imagers will be applicable to other problems related to space science and can be also deployed on the Space Station and on the ground.
