Abstract

An advanced Fabry-Perot interferometer with an innovative focal plane detection technique called the circle-to-line interferometer optical (CLIO) system and high quantum efficiency CCD has been developed and field tested. During the field test at Ann Arbor, Michigan, 9 interference orders were collected simultaneously for the OH(7,3) P₁(3). A signal-to-noise ratio (SNR) of 10 - 100 was achieved with 1-minute integration. Compared with conventional FPI, the CLIO-FPI is more sensitive and capable of collecting airglow data at much higher temporal resolution. The first operational CLIO-FPI is deployed at the Polar Cap Observatory (PCO) at Resolute, Northwest Territories, Canada (74 degree(s)54' N, 94 degree(s)54' W), in 1994. This new instrument is expected to enhance our ability to study the Earth's mesosphere and lower thermosphere.
