Abstract
As part of an ongoing investigation of airglow emissions from space, we have developed an intensified CCD imaging spectrograph for a sounding rocket project called General Excitation Mechanisms In Nightglow (GEMINI). The instrument, known as Limb Imaging Spectrograph for Airglow (LISA) will be used to measure the limb profiles of some important nighttime airglow emission features. The GEMINI rocket is to be launched from White Sands Missile Range, New Mexico, in early 1993. The payload will be three-axis stabilized and absolute pointing will be derived from a star video camera. In this paper the imager design is discussed and we present the results of some laboratory tests performed using an artificial source of the oxygen nightglow emission.
